can someone answer this 2 sample problems. thank you

2. A tank, elevated on a 4-ft high wooden platform is exposed to the atmosphere and the minimum liquid level inside it is 1 m. Water is being pumped from the tank. Determine the NPSH of a pump which is connected to it, handling 220, 500 lb/hr water at 537R via a 5-in schedule 40 steel pipe, 60 ft long. The suction nozzle of the pump is 0.4m above ground level. 3. In a steel annular channel, water (at 293.15 K) is flowing at a rate of 0.56 cubic feet per second. The channel is made of 12 and 1 \A in. schedule 40 pipes. Calculate the change in pressure through the channel if its length is 240 in
