A vertical piston-cylinder device has a piston diameter of 11 cm and piston mass of 40 kg. the atmospheric
pressure is 0.10Mpa and the local gravity is 9.79 m/s2. Determine the absolute pressure of the gas within the device.
A 7 lbm piece of steel is subjected to a vertical force of 8 lbf. The local gravity is 31.1 ft/s2, and frictional effects are neglected. Determine the acceleration of the mass if the external vertical force is (a) downward, (b) upward in ft/s2.
A bell jar 250mm in diameter sits on a plate and is evacuated until a vacuum of 700mmHg exists. The local barometer reads 760mmHg. Find the absolute pressure inside the jar, and determine the force required to lift the jar off the
plate. Neglect the weight of the bell jar.
Two liquid streams are pouring in a container, 8 in. diameter and 15in. high. The mass flow rate of stream A is 1.2
lb/sec and the volume flow rate of B is 0.035 ft3/s. If the specific gravities of A and B are 1.1 and 0.9, respectively, in how many seconds will the container be filled? What is the gage and absolute pressure at the bottom of the filled tank in psia.
The gage pressure of a gas inside a tank is 25kPa. Determine the vertical height, in meters, of liquid within a manometer attached to the system if the fluid at room temperature is (a) water, (b)mercury (ρ=13,600kg/m3), and (c) an oil with a specific gravity of 0.88 and g=9.75 m/s2
A vertical storage tank initially contains water (ρ=1000kg/m3) at a depth of 4m. Immiscible oil with a specific gravity of 0.88 is added until the total liquid height is 10m. If the barometer pressure is 97.2kPa and g=9.80m/s2, determine the
absolute pressure at the bottom of the water, in kPa and bars.
A submarine is cruising at a depth of 280 m in seawater with a specific gravity of 1.03. If the inside of the submarine is
pressurized to standard atmospheric, determine the pressure difference across the hull in (a) kPa, (b) bars. The average local gravity is 9.70m/s2.
A pilot notices that the barometer pressure outside his aircraft is 800 mbars. The airport below the plane reports a barometric pressure of 1020 mbar. If the air density averages
1.15 kg/m3 and the local gravity is 9.70 m/s2, determine the height of the aircraft above the ground, in meters.
