The flow rate of water flowing in a 3 m wide channel is to be measured with a sharp crested triangular weir, where the apex is 0.5 m above the channel bottom with a notch angle of 60°. If the flow depth up stream is 1.5 m. determine the volumetric flow rate of water through the channel. Take C, as 0.6.

Determine the Reynolds number for a flow of 25 ° C water in a 1 in diameter sanitary pipe at a rate of 0.25 kg / second. What are the flow characteristics?

A horizontal 10-cm-diameter jet of water strikes a vertical plate. Determine the velocity issuing from the jet if a force of 1000N is needed to:  (1) Hold the plate stationary (2) Move the plate away from the jet at 10 m/s (3) Move the plate into the jet at 10 m/s

Choose the correct option: According to Darcy's Law, the flow is considered to be: a) Laminate b) Tortuous c) Turbulent d) Systematic
