A cylindrical tank having a diameter of 5 m. and 8 m high is full of water. There is an orifice at the bottom of the tank having an area of 0.02 m?. A. Compute the coefficient of discharge C if it takes 746.21 sec to lower the water surface from 8 m to 3m. B. Compute the coefficient of discharge C if it takes 746.21 sec to lower the water surface from 8 m to 0m. C. Compute the coefficient of discharge C if it takes 746.21 sec to empty the tank.

Situation 7: From reservoir A whose water surface elevation is 225 m. Water is pumped through a 350 mm pipe across a valley at a second reservoir B at a elevation of 240 m. During pump, the pressure is 570 kPa at a point C and at elevation of 195 m. Assume that the headloss in the pipe from reservoir A to point C is 30 times its velocity head and from point C to reservoir B is 50 times its velocity head 23. Compute the discharge in the pipeline in L/s 24. Compute the head added by the pump 25. Compute the horsepower exerted by the pump IVA E1225 m El 240 m El 195 m

A cylindrical tank of water is 20 m in diameter and 3.5 m tall. There is a 1.0 cm diameter hole at the bottom from which water is leaking. A feeder pipe at the top of the tank, 4.0 m above the ground delivers water at a rate of 0.02 m/min. Ir the tank is initially half full, tal what is the water flow rate in m^3/sec from the top feeder pipe? (bi what is the pressure at the bottom of the tank? (Hint: Bernoul's principle) () what is the water speed at the bottom? (d) what is the leaking flow rate at the bottom? fe) at what rate is the volume of water changing? (Assume the tank is open to air at the top)
