Oil is flowing at the rate of 0.015 m³/s in the system shown in Fig. 11.17. Data for the system are as follows:
–  Oil specific weight = 8.80 kN/ m³
–  Oil kinematic viscosity = 2.12 × 10^ˆ’5m²/s
–  Length of DN 150 pipe = 180 m
–  Length of DN 50 pipe = 8 m

–  Elbows are long-radius type
–  Pressure at B = 12.5 MPa

Considering all pipe friction and minor losses, calculate the pressure at A.
