A pressure washer service comes to the house with a tanker truck full of water. The pressure on the tank is maintained at Pw. The water level in the tank is ht from the ground (ht = 8 ft). From the tank, the fluid moves through a hose of 1 inch diameter which is 100 ft long. At the end of the hose there is a friction-less nozzle. The end of the nozzle is 1/4 inch in diameter. The nozzle is held hn above the ground (hn = 3 ft). The exit velocity out of the nozzle for an effective powerwash should be vnozzle = 64 ft/s. a. [15] Determine the required pressure Pw (psig) in the tank at the indicated conditions neglecting friction. Make sure to show your control volume, list all assumptions made, include units, and box your final
