You wash your roof with a water hose at a height of 8.0 m above the ground. You connect two garden hoses to reach the roof, one with a radius of 0.40 cm and the other with a radius of 0.50 cm. The smaller hose is held on the roof and the larger hose is attached to a faucet at ground level, as shown in the image below. You want the exit speed of the water out of the smaller hose on the roof to be 6.0 m/s, and you know the water moves in the large hose but do not know the speed of the water within the large part of the hose. What should the absolute pressure (in Pascals) in the large hose be at ground level? Atmospheric pressure is 1.01x105 Pa. V1= 6.0 m/s r,=0.40 cm 8.0 m r2=0.50 cm

Calculate the resultant force required in kN to hold a 90° elbow in place when attached to DN 150 Schedule 40 pipes carrying water at 0.1768 m3/s and 1 050 kPa. Neglect energy lost in the elbow. Do not include direction for the final answer! NB: Assume a water density of 1000 kg/m3 and use appropriate appendix to obtain necessary data. Hint: Draw a diagram showing the pipe system with the bent at the bottom right corner, water flowing from left to right then up to help you analyse the problem.

Complete Solution please, thanks. 3. A vertical circular stack 30 m high converges uniformly from a diameter of 6 m at the bottom and 4.5 m at the top. Gas with a unit weight of 0.12 N per cubic meter enters the bottom of the tank with a uniform velocity of-assume values with decimals between 3 to 4 m per second- enters the stack. The unit weight increases by 7.5 percent every 2 meters. Find the velocity of flow at every 5 meters along the stack.
A large water tank is connected to a small nozzle located 5 ft below the water surface in the tank (Figure a). The nozzle diameter at the exit is 1 in. Find the flow rate through the nozzle. We now attach a diffuser to the nozzle (Figure b). Will the flow rate a) increass, b) remain the same, or c) decrease?
Water flows through a horizontal tapered pipe with a diameter of 300 mm at one end and 200 mm at other end. If the velocity of the water at bigger end is 2.5 m/s, find the velocity of water at smaller end.
Water is pumped into a fire hose through a 6 cm diameter pipe with speed 1m/s. The water in the fire hose flows with a pressure of 200000 Pa. At the end of the fire hose is a nozzle (small hole). The pressure decreases to atmospheric pressure (101300 Pa) when the water leaves the nozzle from the hose. There is no change in height moving from the hose to the nozzle. 1. What is the water speed in a 4 cm diameter fire hose? 2. What is the velocity of the water exiting the nozzle (p=1000kg/m³)? 4. What is the diameter of the nozzle? 3. A Fireworker now connects an additional flexible tube to the nozzle (tube and nozzle has same diameter). He lifts the tube to a height of 1 meter above the ground. At what speed does the water come out of the tube? (hint - the pressure at the exit is still atmospheric)
115 m turbine 2 In the above example problem, a hydroelectric turbine at the base of a dam is shown schematically. The height of the water above the turbine station given as 115 m. This turbine produces 4.6 MW of electricity, and you may assume the losses in the system to be equivalent to 10 m of head of water. The diameter of the pipe at the turbine exit is 0.75 m, and the velocity of water exiting from the pipe is 12.5 m/s. Caleulate the efficiency of the turbine.

3. A pipe with varying cross-sectional areas is set up vertically as shown in the drawing. Water enters the pipe from the top wider end at a speed of 300 cm/s. Calculate (a) the mass flow rate of water (the amount of mass entering/exiting the piper every second) and (b) the water pressure at the bottom narrower end section of the piper.
