Question: Water is flowing with 0.15 m/s flow rate inside a horizontal pipe with a diameter of D-30 cm. After a sudden contraction, the pipe diameter

Water is flowing with 0.15 m/s flow rate inside a horizontal pipe with a diameter of D-30 cm. After a sudden contraction, the pipe diameter decreases to D2-15 cm. If the pressure of the water in the first pipe is P-500 kPa, calculate the pressure of water in the second pipe. (Please consider that the flow is turbulent and friction losses are only due to sudden contraction. P-1000 kg/m).
