Q3- A centrifugal pump draws water from a sump through a vertical 15 cm pipe diameter. The pump has a horizontal discharge pipe 10 cm diameter which is 3.5 m above water level in the sump. While pumping 30 l/s, gages near the pump at entrance and discharge read -35 kPa and+180 kPa respectively. The discharge gauge is 0.5 m above the suction gauge. Determine the power output of the pump. * P 10.5 m 3.5 m

From a very large tank with an absolute pressure of 3 bar, the water is discharged to the atmosphere by means of 2 smooth pipes of 100 m length, 1 m and 50 m long, connected in series. The height difference between the water level in the tank and the outlet is 50m, and the diameters of the pipes are 50mm and 100mm, respectively. In addition, a 500kPa turbine is placed on the 2nd Pipe. a) Draw the system roughly, show the dimensions on it.b) Calculate the exit velocity of the water from the 2nd pipe, ignoring the local losses.
