Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...

Air at 100 kPa and density of 1.2 kg/m3 flows upward through a 5-cm diameter inclined duct at a rate of 50 L/s. The duct diameter is then reduced to 4 cm through a reducer. The pressure change across the reducer is measured by a water manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.1 m. Determine the differential height between the fluid levels of the two...

Question 3 (40 marks) (a) Air enters a horizontal nozzle with a velocity of 1 m/s, a pressure of 2 bar and a temperature of 350 K. At exit from nozzle, the air temperature is 450 K. The combined rate of specific heat transfers, and specific work transfers, w to the air as it passes through the nozzle is 150 kJ/kg. Assume that the air flow is steady and air can be treated as perfect gas with = 1005 J/(kg.K)....
