Water flows through a right angle valve at the rate of 1000 lbm/s as shown in the figure. The pressure just upstream of the valve is 90 psi and the pressure drop across the valve is 50 psi. The inside diameters of the valve inlet and exit pipes are 12 and 24 in. If the flow through the valve occurs in a horizontal plane (no elevation change), determine the x component of the force exerted by the valve on the water.
