Which

parameter is not related in the Bernoulli equation?

A

hydraulic turbine is used to generate power by using the water in a dam. The

elevation difference between the free surfaces upstream and downstream of the

dam is 120 m. The water is supplied to the turbine at a rate of 150 kg/s. If

the shaft power output from the turbine is 155 kW, the efficiency of the

turbine is 

A water

tank initially contains 140 L of water. Now, equal rates of cold and hot water

enter the tank for a period of 30 minutes while warm water is discharged from

the tank at a rate of 25 L/min. The amount of water in the tank at the end of

this 30-min period is 50 L. The rate of hot water entering the tank is
