In Figure Q3, the tank is depicted as holding 4 kg of air at an absolute pressure of 350 kPa and a temperature of 18°C. If an additional 0.8 kg of air is introduced into the tank, causing the temperature to increase to 38°C, calculate the resultant pressure within the tank.

If 10 ft of atmospheric air at 300 F temperature are compressed until the volume decreases to 1 ft and the temperature decreases by 200 F, what will be the resulting pressure of the air in psig?

2. If 100 ft of atmospheric air at zero Fahrenheit temperature are compressed to a volume of 1 ftat a temperature of 200-F, what will be the pressure of the air in psi?

2. If 100 ft3 of atmospheric air at zero Fahrenheit temperature are compressed to a volume of 1 ft³ at a temperature of 200 F, what will be the pressure of the air in psi?

Aclosedtank of a certain gas receives heat from being exposed to the sun. The bourdon pressure gauge initially reads 20 kpa but after some time it reads 30 kpa. Find the final absolute pressure of the gas inside

Two spheres, each 6 ft in diameter, are connected by a pipe in which there is a valve. Each sphere contains helium at temperature of 80°F. With the valve closed, one sphere contains 3.75 lb and the other 1.25 lb of helium. After the valve has been open long enough for equilibrium to obtain, what is the common pressure in the spheres if there is no loss or gain of energy.

Find h when the pressure in tank B is 21 kPa.

When the system below is in equilibrium, there is mercury in the manometer. Calculate the absolute and gauge pressure of the gas in the tank? Take the height of the mercury to be 29 cm. Take the density of mercury as 13290 kg/m3.

A balloon weighs 270 lbs and has a volume of 14,900 ft3 is filled with helium, which weighs 0.0112 lb/ft3 at the temperature and pressure of the air, which weighs 0.0807 lb/ft3 . What load will the balloon support?

The Super Soaker XP30 is a marvel of hydraulic dispersion weaponry. By pumping on the handle, you charge the chamber to high pressure. The pressure is maintained until you pull the trigger at which point the water (? = 1000 kg/m3) is released at high velocity. You have charged your pressure chamber to an absolute pressure of P1 = 675500 Pascals, much higher than today's outside air pressure of 101300 Pascals. The pressure chamber is location at a height of y1 = 0.117 meters above the exit point. The exit point has a small opening with radius r = 0.0038 meters. Determine all the following: a) The velocity at which the water exits the Super Soaker: v2 = m/s b) The mass flow rate through the exit: kg/sec c) The volume flow rate through the exit: m3/sec
