1.Water at 10°C is flowing at 0.075 m 3 /s. Calculate the weight flow rate and the mass flow rate

2.The refrigerant (SG=1.08) flashes into a vapor, its specific weight is 12.50 N/m 3 . If the weight flow rate remains at 28.5 N/h, compute the volume flow rate.

3.Water flows at 1.20 m/s in a circular section with a 150 mm inside diameter. Calculate the velocity of flow in a 300-mm-diameter section connected to it

4.Figure below shows a fabricated assembly made from three different sizes of standard steel tubing listed in Appendix G.2. The larger tube on the left carries 0.072 m 3 /s of water. The tee branches into two smaller sections. If the velocity in the 50-rnm tube is 12 m/s, what is the velocity in the 100-mm tube?

5.Define a Newtonian fluid
6.Define a non-Newtonian fluid.

7.Write Water at 10°C flows from a large reservoir at the rate of 1.5 x 10 -2 m 3 /s through the system shown in figure below. Calculate the pressure at B

8.Benzene (SG = 0.86) at 60°C is flowing at 25 L/min in a DN 25 Schedule 80 steel pipe. Is the flow laminar or turbulent?

9.Benzene at 60°C is flowing in a DN 25 Schedule 80 steel pipe at the rate of 20 L/min. The specific weight of the benzene is 8.62 kN/m 3 . Calculate the pressure difference between two points 100 m apart if the pipe is horizontal
