In an irrigation system sometimes water must be pumped over long distances. Consider a system that consistes of a 1 m diameter, 2 km long commercial steel pipe, which connects a river to an irrigation canal.
a) Neglecting minor losses, determine the pumping power required (in kW) to produce 2.5 m^3/s of water.
b) What would the pumping power be if the canal's e;evation is 50 m higher than that of the river? Use water properties at 15(degrees)C
A box of mass M=500 kg hangs by a rope from a beam with dimensions a=2.0 m and b=3.0 m. The beam has mass m=85 kg. Find the tension T_c in the cable and the magnitude of the net force F exerted on the beam by the hinge.
