1. For the fire hose shown below, a pressure of 50 psi is measured entering the
nozzle from the 4 in diameter hose. If the diameter of the exit nozzle is 2 inches,
would you be able to hold the fire hose? Assume t
Viscous Flow in Pipes
1. Water at 20C flows through a 200mm diameter pipe at 2.5 m/s. Is the flow
laminar or turbulent?
2. Oil (S.G. = 0.9, = 3.0x10-4 m2/s) enters a 50mm diameter tube at a flow rate Q =
1L/s. Calculate the entrance leng
