As shown in the figure, the water flows from the ground floor of a three-storey house to the second floor through pipes of 20 mm diameter (average roughness of the pipe material = 0.0015 mm) at a volumetric flow rate of 0.75 L / s. Water is discharged from the system to atmospheric pressure through a tap with a 12 mm diameter outlet. There are 4 winged elbows, one ball valve and one faucet throughout the installation. Calculate the effective pressure at point 1. (pwater=998 kg/m3, uwater=1.12x10-3 Pa s, g=9.81 m/s2)

A pressurized tank and piping system are shown in the figure. The tank pressure is maintained at 175 kPa. The line is made of 12 m of 1 std type M copper tubing and it conveys gasoline (octane). What is the expected flow rate through the line? All fittings are soldered (same as flanged) and regular. 4 m 175 kPa 1 m

Example -5.2- It is required to pump cooling water from storage pond to a condenser in a process plant situated 10 m above the level of the pond. 200 m of 74.2 mm i.d. pipe is available and the pump has the characteristics given below. The head loss in the condenser is equivalent to 16 velocity heads based on the flow in the 74.2 mm pipe. If the friction factor = 0.003, estimate the rate of flow and the power to be supplied to the pump assuming n = 0.5 Q (m³/s) 0.0028 0.0039 0.005 0.0056 0.0059 Ah (m) 23.2 21.3 18.9 15.2 11.0
