Arectangular channel, laid out on a 0.5° slope, delivers a flow rate of 5,000 gal/min in unifornm flow when the depth is ft and the width is 3 ft. (a) estimate the value of manning's factor n b) what water depth will triple the flow rate?

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
