A dam is situated at a height of `300m` above sea level ,It supplies water to a power house which is at a height of `60m` above sea level, `1000kg` of water passes through the turbine per second. If the efficiency of the system is `80%`, the electrical power out put is, `(g=10ms^(-2))`

A dam is situated at a height of 550 m above sea level and supples water to a power house which is at a height of 50 m above sea level. 2000 kg of water passes through the turbines per second. What would be the maximum electrical power output of the power house if the whole system were 80% efficient

A dam is situated at a height of 550m above sea level and supplies water to a power house which is at a height of 50 m above sea level. 2000 kg of water passes through the turbines per second. What would be the maximum electrical power output (in MW ) os the power house if the whole system were 60% efficent ?

An engine pumps up 100 kg water through a height of 10 m in 5 s . If effcienecy of the engine is 60% . What is the power of the engine? Take g = 10 ms^(2) .

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)) .

Water is poured from a height of 10m into a mepty vessel at the rate of 1 litre per second . If the weight of the vessel is 10 kg ten th weight indicated at time t=60s will be

A motor is to be used to lift water from a depth of 10 m & discharging it on ground level at a speed 10m//s if 2 kg of water is lifted per second & the efficiency of motor is 40% The minimum power of the motor should be nearly :
