Water flows steadily through a pipe with ID 35 mm. This pipe expands suddenly to an inner diameter of 75 mm and then stays at that diameter. The flow speed in the 35 mm pipe is 32 m/s. The water gage pressure in the thinner pipe is 510 kPa. 1. What is the pressure at the entrance to the thicker section of the pipe? Is the pressure there larger or smaller than in the thin pipe section?

Q2 Using a centrifugal pump, process fluid is pumped from the bottom of one distillation column to another. The line is a standard commercial steel pipe 75 mm internal diameter. From the column to the pump inlet, the line is 25 m long and contains six standard elbows and a fully open gate valve. From the pump outlet to the second column, the line is 250 m long and contains ten standard elbows, four gate valves (operated fully open) and a flow-control valve. The fluid level in the first column is 4 m above the pump inlet. The feed point of the second column is 6 m above the pump inlet. The operating pressure in the first column is 1.05 bara and that of the second column 0.3 barg. Determine the operating point on the pump characteristic curve when the flow is such that the pressure drop across the control valve is 35 kN/m2. The physical properties of the fluid are: density 875 kg/m3, viscosity 1.46 mN m-2 s. Also, determine the NPSH, at this flow-rate, if the vapour pressure of the fluid…

c) A nozzle is fastened to the end of a U-tube with dimensions as shown in Figure Q2c. The nozzle exhausts into atmospheric pressure at 100 kPa; neglect friction and compute the force exerted on the U-tube by the water. If the force required to hold the nozzle is 850 N, determine the inlet pressure. 5 CRN 31896 V = 1 m/s 5 cm diameter 1 cm diameter Figure Q2c

At L=0, the liquid flows inside the nozzle has a specific gravity S=6.1, at L=0, the velocity is 2 m/s while at L=70 cm, the velocity is 6 m/s. Assume steady and inviscid flow. The velocity varies linearly with distance through the nozzle. 70 cm 60 em Liguid
