answer: 4.76 kg

Determine the mass of air in a 2 m3tank if the air is at room temperature, 20 °C, and the absolute pressure within the tank is 200 kPa (abs).

63.78 C = 64 C

Nitrogen is compressed to a density of 4 kg/m3under an absolute pressure of 400 kPa. Determine the temperature in de grees Celsius.

A. 0.0214 kg/m3
B Pmars/ Pearth = 1.75%

The temperature and pressure at the surface of Mars during a Martian spring day were determined to be and 900 Pa, respectively. (a)Determine the density of the Martian at mosphere for these conditions if the gas constant for the Martian atmosphere is assumed to be equivalent to that of carbon dioxide. (b)Compare the answer from part (a) with the density of the Earth’s atmosphere during a spring day when the temperature is and the pressure 101.6 kPa (abs).

A closed tank having a volume of is filled with 0.30 lb of a gas. A pressure gage attached to the tank reads 12 psi when the gas temperature is There is some question as to whether the gas in the tank is oxygen or helium. Which do you think it is? Explain how you arrived at your answer.

Density: 6.44 × 10^-3 slugs/ ft³
Weight: 0.622 lb

A tire having a volume of 3 ft3contains air at a gage pres sure of 26 psi and a temperature of 70 F. Determine the density of the air and the weight of the air contained in the tire.

4.63 m³

A compressed air tank contains 5 kg of air at a temperatureof 80 °C. A gage on the tank reads 300 kPa. Determine the volume of the tank.

answer: 98.7 psia

A rigid tank contains air at a pressure of 90 psia and a temperature of 60 F. By how much will the pressure increase as the temperature is increased to 110 F?

57.92

The density of oxygen contained in a tank is 2.0 kg/m3when the temperature is 25 C. Determine the gage pressure of the gas if the atmospheric pressure is 97 kPa.

668 lb

The helium-filled blimp shown in Fig. P1.52 is used at var ious athletic events. Determine the number of pounds of helium within it if its volume is 68,000 ft3and the temperature and pres sure are 80 °F and 14.2 psia, respectively.

Develop a computer program for calculating the density of an ideal gas when the gas pressure in pascals 1abs2, the tem perature in degrees Celsius,and the gas constant in are specified. Plot the density of helium as a function of tempera ture from 0 °C to 200 °C and pressures of 50,100,150,and 200 kPa (abs).
