What are the energies possessed by a liquid ? Write down their equations. |
|
Answer» Solution :A liquid in motion possesses FOLLOWING three types of energy . (i) Kinetic energy : It is the energy possessed by a liquid by virtue of its motion. K.E. = `1/2 m v^2` K.E. per unit MASS = `(1/2 mv^2)/(m) = (v^2)/2` (ii) Potential energy : It is the energy possessed by a liquid by virtue of its HEIGHT above the GROUND level. P.E. = mgh P.E. per unit mass `= (mgh)/(m) = GH` (iii) Pressure energy = It is the energy possessed by a liquid by virtue of its pressure. Pressure energy per unit mass `= P/(m//v)` |
