The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in Figure Q5. Determine the gage pressure of air in the tank if h,=0.3 m, ha=0.4 m, and hz=0.5 m. Take the densities of water, oil, and mercury to be 1000 kg/m², 850 kg/m?, and 13,600 kg/m², respectively.

The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in Figure 1. Determine the gage pressure of air in the tank if h1=26cm, h2=45cm, and h3-58cm. The specific gravity of mercury and oil are given to be 13.6 and 0.85 respectively. AIR WATER Mercury Figure 1

Question 2 (30 marks) (a) A fluid flowing into a nozzle with specific enthalpy of 2980 kJ/kg and the velocity is 80 m/s. At the exit of the nozzle, the specific enthalpy of the fluid drops to 2670 kJ/kg. The nozzle orientation is horizontal and the heat loss is negligible. Given that the nozzle inlet area is 0.25 m2 and the specific volume of the fluid is 0.2 m2/kg, calculate the velocity of the fluid at exit, the mass flow...

2. The basic barometer can be used to measure the height of a building. If the barometric readings at the top and at the bottom of a building are 675 and 695 mmHg, respec- tively, determine the height of the building. Take the densi- ties of air and mercury to be 1.18 kg/m2 and 13,600 kg/mº, respectively. 3. Freshwater and seawater flowing in parallel horizon- tal pipelines are connected to each other by a double U-tube manometer, as shown in...

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)....
