The nozzle shown discharges water at the rate of 200 gal/min. Knowing that at both B and C the stream of water moves with a velocity of magnitude 100 ft/s, and neglecting the weight of the vane, determine the force-couple system that must be applied at A to hold the vane in place (1 ft3 = 7.48 gal).
Coal is being discharged from a first conveyor belt at the rate of 120 kg/s. It is received at A by a second belt that discharges it again at B. Knowing that v1 = 3 m/s and v2 = 4.25 m/s and that the second belt assembly and the coal it supports have a total mass of 472 kg, determine the components of the reactions at C and D.
A stream of water flowing at a rate of 1.2 m3/min and moving with a speed of 30 m/s at both A and B is deflected by a vane welded to a hinged plate. Knowing that the combined mass of the vane and plate is 20 kg with the mass center at point G , determine (a) the angle 0, (b) the reaction at C.
