A decorative fountain for a casino is designed to shoot a stream of water straight up in the air.  For the stream to reach a height of 84 feet in the air, what pressure must exist at the nozzle inlet.  The nozzle has an inlet diameter of 4.0 inches and an outlet diameter of 2.0 inches.

(Just Question a.) A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure.     If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe?   a. What is the volume flow rate through the smaller pipe?

Water is poured into the tube shown in Figure P4.46 until it occupies 15 in. of the rube's length. Then oil (S.G. = 0.87) having a volume of 1 /3 of water volume is poured in the right leg. Determine rhe difference between water and oil surfaces.

Somewhere along the middle of a horizontal pipe which has a constant diameter of 10 cm a water pump is installed. At the inlet of the horizontal pipe, the pressure is 101,325 Pa. The water then exits the pipe with a pressure of 130,000 Pa. What is the head added by the pump in meters? Take the specific weight of water as 9810 N/m^3. Round your answer to 3 decimal places.
