Suppose the water from the fire hose described in Problem 7.45 strikes the device shown in Figure P7.17. Neglecting the change in water elevation as it moves over the device, determine the magnitude and direction of the force exerted by the water stream on the device.

Problem 7.45

Water from the nozzle of a fire hose strikes a flat a stop sign as shown in Figure P7.16. Water exits the nozzle at a velocity of 45 ft/s through a circular exit port of diameter 5 in.

(a) Calculate the horizontal reaction force on the stop sign support.

(b) What, if anything, can you conclude about the fluid flow characteristics in the vertical direction for this situation?
