1.Water at 20 C flows in a conduit with a cross-section shaped in the form of an equilateral triangle. The cross-sectional area of the conduit is 100 sqaure meters and e=0.045 mm. If the friction head loss is 1 m in 50 m, find the approximate flow rate.

2.A channel of a rectangular section is to take a certain discharge Q at critical flow; prove that for the wetted perimeter, P=b+2y to be minimum, the water depth must be three-quarters of the width
