Define the following terms vertical line, bubble line.

Answer»

In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is FORMED when heating a liquid consisting of two or more components.[1][2] Given that vapor will probably have a DIFFERENT composition than the liquid, the bubble point (along with the dew point) at different compositions are useful data when designing distillation systems.[3]
For a single component the bubble point and the dew point are the same and are REFERRED to as the boiling point.





























A vertical line is ONE the GOES straight up and down, parallel to the y-axis of the coordinate plane. All points on the line will have the same x-coordinate. In the figure above, drag either point and note that the line is vertical when they both have the same x-coordinate. A vertical line has no slope.

Discuss in brief the principles of surveying.

Answer»

There you go:

The general principles of surveying are:

To work from the whole to the part

To LOCATE a new station by at least two measurements (linear or angular) from fixed reference points.

According to the first PRINCIPLE, the whole area is first enclosed by MAIN stations (i.e. Controlling stations) and main survey lines (i.e. controlling lines). The area is then divided into a number of parts by forming well conditioned triangles. A nearly EQUILATERAL triangle is considered to be the best well-conditioned triangle.The main survey lines are measured very accurately with a standard chain. Then the sides of the triangles are measured. The purpose of this process of working is to prevent accumulation of ERROR. During the procedure, if there is any error in the measurement of any side of a triangle, then it will not affect the whole work. The error can always be detected and eliminated.

According to the second principle, the new stations should always be fixed by at least two measurements (linear or angular) from fixed reference points. Linear measurements refer to horizontal distances measured by chain or tape. Angular measurements refer to the magnetic bearing or horizontal angle taken by a prismatic compass or theodolite.

In chain surveying, the positions of main stations and directions of main survey lines are fixed by tie lines and check lines.

Write about parts of the Transit Theodolite. Explain in detail.

Answer»

Theodolite is used for measuring the horizontal and vertical angles.Here we are going to learn about different transit theodolite PARTS.

Transit theodolite parts ( Parts and fuctions)

Telescope of theodolite

The telescope is the major components of theodolite, Telescope is mounted on a spindle or horizontal axis or trunnion axis. Internal focusing type telescope is widely used.

Vertical Circle of transit level

Vertical circle is another important theodolite parts, a circular graduated ring is attached to the horizontal. With the help of vertical circle, we can measure the vertical angle of the line of sight with the horizontal axis.



Index frame or T frame

Two verniers are fitted to read the vertical circle. Clip SCREW is used for SLIGHT adjustment. Altitude bubble is placed at the top of index frame.

Transit level head

Transit level head consists of two parallel triangular plates. These triangular plates are called tribrach plates. It is another essential theodolite parts.

Plumb Bob

Plumb bob is used for the temporary adjustment of the theodolite.The temporary adjustment of a theodolite are

Centering

Leveling

Elimination of parallax.

Compass

Compass is one of the MAIN parts of theodolite. Compass is used to measure the angle between the NORMAL line and line of sight. There are two types of the compass, prismatic compass, and surveyor compass

Tripod

Tripod the main part needed for a theodolite and it is used for supporting theodolite.

What is tacheometry? What are different systems of tacheometric measurements?

Answer»

a method of angular surveying in which the horizontal DISTANCE from the instrument to the staff stations are determined from instrumental observations only.


Here are TWO examples

Stadia System of TACHEOMETRY;

In the stadia system the horizontal distance to the staff Station from the instrument station and the elevation of the staff station concerning the line of sight of the instrument is obtained with only one OBSERVATION from the instrument Station.

Tangential System of Tacheometric Surveyinh

In this system of tacheometric surveying, two observations will be necessary from the instrument station to the staff station to determine the horizontal distance and the difference in the elevation between the line of collimation and the staff station.


The only advantage of this method is that this survey can be conducted with ordinary transit theodolite.

Find the vector of magnitude 11 units in the direction opposite to pqwhere p(1 3 2) and q(-1 0 8)

Answer»

<P>The vector with INITIAL POINT P(1,3,2) And TERMINAL point Q(-1,0,8) is given by

PQ = (-1-1)i + (0-3)j + (8-2)k

PQ = - 2i - 3j + 6K

QP = -PQ = - 1(- 2i - 3j + 6k)

QP vector = 2i +3j - 6k

IQPI = \sqrt{(2^2) + (3^2) + (-6^2)}

IQPI = \sqrt{49} = 7

Therefore unit vector in direction of QP vector is given by

QP unit vector = QP vector/IQPI

QP unit vector = (2i +3j - 6k)/7

QP unit vector = (2/7) i + (3/7) j - (6/7) k

Hope my answer and picture attached will satisfy you.

The elevator shown in figure (5−E5) is descending with an acceleration of 2 m/s2. The mass of the block A is 0.5 kg. What force is exerted by the block A on the block B?Figure

Answer»

Answer:

The force exerted by the block A on the block B is 4 N.

Explanation:

When the ELEVATOR is descending, a pseudo-force acts on it in the UPWARD direction.

From the free-body DIAGRAM of block A,

mg-N=ma

N=m(g-a)

⇒N=0.5(10-2)

=4 N

So, the force exerted by the block A on the block B is 4 N.

Study on the effect of regenerative system on power type relative internal efficiency of nuclear steam turbine

Answer»

ABSTRACT and Figures

NUCLEAR steam turbine use wet steam as working medium, which is unable to determine the enthalpy drop type relative internal efficiency through exhaust enthalpy of steam, but the power type relative internal efficiency avoids this question. This PAPER introduced the calculate method of power type relative internal EFFICIENCE, and then took a 900MW nuclear steam turbine for example, calculated the power type relative internal efficiency when the factors of regenerative system are changed. The result shows that when the factors of regenerative system are changed in a large range, the power type relative internal efficiency is nearly changeless, so the effect of regenerative system on relative internal efficiency can be neglected. At last, the independence between relative internal efficiency and ideal cycle heat efficiency is calculated and analyzed.

What is the phase difference between voltage across the inductor and a capacitor in an ac circuit?

Answer»

The phase difference is <= 90 DEGREES. It is customary to use the angle by which the voltage LEADS the current. This leads to a positive phase for INDUCTIVE circuits since current lags the voltage in an inductive CIRCUIT. The phase is negative for a CAPACITIVE circuit since the current leads the voltage.
