7.45 If the fluid motor has an efficiency of 78 percent, how much power is delivered by the motor? 15-in Schedule 80 steel pipe 25-in Schedule 80 steel pipe Oil -Motor Flow 38.5 in Mercury sg = 13.54 Answer is 1.24 Hp. Please shw how to get ture.

1. An 80 mm schedule 40 steel pipe is 1800 m long and carries a lubricating oil between 2 points A and B such that the Reynolds number is 1200.  Point B is 10 m higher than point A.  The oil has a specific gravity of 0.85 and dynamic viscosity of 6.51 X 10-1 Pa.s.  If the pressure at A is 345 KPa, calculate the pressure @ B.   2. Determine the energy loss for a sudden contraction from a 4 in schedule 80 steel pipe to a 1.5 in schedule 80 pipe for a flow rate of 250 gal/min.     3. Determine the equivalent length in meters of pipe of a quarter open gate valve placed in a DN 250 schedule 40 pipe.

Please give a detailed explanation, Don't use chatgpt.
