Question
Water flows in pipes A and B and converges into pipe C as shown in the figure. If the flow
rate at pipe C is 50 L/s and the velocity at pipe A is 4 m/s, determine the velocity (in m/s) of
water at pipe B.
da = 100 mm
dc = 300 mm

dB = 200 mm
a. 0.019
b.0.031
c.0.592
d.0.707
The 75-mm water main pipe in your street has a pressure of 200 kPa and carries 25 lps of
flow. You want to store water into an elevated tank, 12 m above the water main, so there is
adequate flow in your 3rd level bathroom. Assume the total losses from the water main to
the water tank is 10 m. Determine the rated power (in kW) of a household pump required if
the pump has an efficiency of 80% and the air pressure in the partially full tank is 300 kPa.
The flow through the pump is 3 lps.
