SOLVE ALL PARTS 4 NEED EXACT ANS STEP BY STEP DONT WASTE MY QUE BY GIVING WRONG ANS

1)Draw control volume 2)write assumptions and solve the following problem 3) Water a flows through a 5-cm-diameter pipe which has a 180 vertical bend. The total length of pipe between flanges 1 and 2 is 75 cm. When the weight flow rate is 230 N/s, p1 = 165 kPa, and p2 = 134 kPa. pipe weight can be neglected, determine the total force that must the flanges must withstand for this kind of flow.

4) two tanks are connected through a 500m long 0.5m diameter pipe which connects with gate valve.pipe entrance is sharp and valve is half open.head difference is 10m friction factor =0.02 find flow rate include both minor and major loss
