At a hydroelectric power plant, the water pressure head is at a height of 300 m and the water flow available is `100 m^3 s^-1`. If the turbine generator efficiency is 60%, estimate the electric power available from the plant `(g=9.8 ms^-2)`

In hydroelectric power plant, the _____________ energy of the flowing water drives the turbine.

An electric pump has 2 kW power. How much water will the pump lift every minute to a height of 10 m ?

A pump lifts 373 kg of water to a height of 10m in 98s. Find the power of the pump. Express it in horsepower.

A cylindrical tank having cross-sectional area A is filled with water to a height of 2.0 m. A circular hole of corss-section area is opened at a height of 75 cm from the bottom. If a//A=sqrt(0.2, then velocity with which waer emerges from the hole is (g =9.8 ms^(-2))

Water is filled in a cylindrical container to a height of 3m . The ratio of the cross-sectional area of the orifice and the beaker is 0.1 . The square of the speed of the liquid coming out from the orifice is (g=10m//s^(2)) .

Determine the pressure required to reduce the given volume by 1%. Bulk modulus of water is 2 xx 10^9 N//m^2

A cylindrical tank is filled with water to a level of 4 m. A hole is opened at a height of 60 cm from bottom. The ratio of the area of the hole to that at cross-sectinal area at cylinder is 0.2. Then the velocity with which water is coming out is (g = 10m//s^(2))

Answer the following questions : What is the acceleration due to gravity at a height h (=radius of the earth) from the surface of the earth ? (g=9.8m/s^2)

Calculate total energy per unit mass possessed by water at a point where the pressure 0.1 xx 10^5N/m^2 with a velocity 0,02 m/s and height of water level from the ground is 10 cm . Density of water = 1000 kg/m^3 , g= 9.8 m/s^2 .
