8. The figure shows a tank within a tank, each containing air. Pressure gage A, which...
A vacuum gage at the intake duct to a fan gives a reading of 4.2 in. of manometer fluid. The surrounding atmospheric pressure is 15.6 lbf/in.2 Determine the absolute pressure inside the duct, in lbf/in.2 The density of the manometer fluid is 49.94 lb/ft3, and the acceleration of gravity is 32.2 ft/s2.
5. If you put air in your tires in La Paz, Bolivia, and your pressure gauge is reading 25 psig, what is the absolute pressure inside the tire, in psia? (The standard atmospheric pressure in La Paz is about 62 kPa!) Answer: between 30 and 35 psia. 2. A manometer like the one we drew in class has water in the column. The side that is open to standard atmospheric pressure is 20 cm lower than the side open to...
6 point A compressed air in a tank is at a gage pressure of 60 in of Mercury (Y=846 Ibtit). Determine the absolute pressure (psial of the air in the tank when atmospheric pressure is 14.7 ptia. Moving to another question will save this response
The figure belows shows a dosed tank holding air and oil to which is connected a U-tube mercury manometer and a pressure gage, with 24-4ft, L2 - 0.5 ft, and L3 - 1.25 ft. The densities of the oil and mercury are 55 and 845, respectively, each in lb/rt. Let 9 -32.2 ft/s? Peware Air QI (55) Mercury (545) Determine the reading of the pressure gage, in Ibf/in? (gage). Page RESOURCES Problem 1.041 The figure belows shows a closed tank...
A manometer connected to a tank gives a column length reading of 12 in of manometer fluid. The surrounding atmospheric pressure is 14.7 psi. Determine the absolute pressure inside the tank in psi and kpa. The density of the manometer fluid is 100 lbm/it' and the acceleration of gravity is 32.2 ft/s. Make sure you show your units clearly.
The figure shows a cylindrical tank of 80 em in diameter which is fully filled with water. In order to increase the flow from the tank to the exit pipe on the left, an additional pressure is applied to the water surface by an air compressor to supply air to the upper air chamber of the tank. The external walls of the tank are exposed to the atmospheric conditions of the area. You are required to determine the hydrostatic conditions...
3. If a water-filled manometer is connected to a tank of CO2, and it shows a 2-inch difference in water level, what is: a. The gage pressure of the gas in the tank, expressed in Pa? b. The absolute pressure of the gas in the tank, expressed in kPa? Assume that the manometer is at sea level, and that the pressure in the tank is higher than atmospheric (i.e. the water in the side of the manometer that is open...
A tank with a volume of 1.3m^3 contains air with a gage pressure of 350kPa. A mercury manometer is attached to the tank and is open to the atmosphere on the other end. The atmospheric pressure is 100kPa and the tank temperature is 27C. What is the height of the mercury in the manometer?
