What are the advantages and disadvantages of direct loading method over open circuit and short circuit test? |
|
Answer» Answer: Now basically we're TALKING about knowing performance of the transformer, i.e, we're trying to find its efficiency. Finding efficiency is done by two methods, 1) Direct 2) Indirect Direct: its direct loading of machine, find input and output by Metering equipment and find efficiency. Advantages: 1) Simple process, 2) no much CALCULATIONS needed, 3) Simple setup 4) Disadvantages: 1) It's not economical to do this test on large rating machines as, just for the sake of test you can't waste large amount energy. 2) You can't get information about the SHARE of different types of losses 3) It's a difficult task arrange different kinds for load (R,L,C) from no load to full load to study performance at different SITUATIONS. |

Find the volume occupied by 34g of NH3 at 27°C and 380mm of Hg pressure. (R= 0.084 L atm K-¹ mol-¹), N= 14.H=1. |
|
Answer» Answer: The ideal GAS equation relating pressure (P), VOLUME (V), and absolute temperature (T) is given as: PV = nRT Where, R is the universal gas constant =8.314Jmol−1K−1 n = NUMBER of moles = 1 T = Standard temperature = 273 K P = Standard pressure = 1 atm =1.013×105Nm−2 ∴V=nRT/P =1×8.314×273/(1.013×105) =0.0224m3 =22.4 litres Hence, the molar volume of a gas at STP is 22.4 litres. |

) Why does the egg sink in pure water and float in brine solution |
|
Answer» Answer: Because the density of the egg is higher than the density of tap water, so it SINKS. ... When ENOUGH salt is ADDED to the water, the saltwater solution's density becomes higher than the egg's, so the egg will then float! The ability of something, like the egg, to float in water or some other LIQUID is known as buoyancy. |

A police jeep on a petrol duty on national highway was moving with a speed of 54km/hr. in the same direction. It finds a thief rushing up in a car at a rate of 126km/hr in the same direction. Police sub – inspector fired at the car of the thief with his service revolver with a muzzle speed of 100m/s. with what speed will the bullet hit the car of thief? |
|
Answer» Answer: Speed of the police jeep = 54km/h Now we will convert the speed from kilometers to meters Speed of police jeep =54km/h 1km/hr =1000m/60x60sec=5/18 m/s = 54 x5/18 =270/18 =15m/s Therefore 54km./hr speed is EQUAL to 15m/s Speed of the police jeep = 54km/h=15m/s MUZZLE speed of the REVOLVER HIT by the police=100m/s Total velocity of the bullet= Speed of the car + muzzle speed= 100m/s + 15m/s= 115m/s Velocity of the thief’s car= 126km/h = 126x 5/18 = 35m/s Therefore 126km./hr speed is equal to 35m/s Velocity of the thief’s car=126km/h= 35m/s Relative velocity of the bullet with RESPECT to thief=Total velocity of the bullet – Velocity of the thief’s car= 115m/s – 35m/s= 80m/s So bullet will hit the car of the thief at a velocity 80 m/s |
