1. A tank contains carbon dioxide maintained at 50 C and 0.5 MPa. The tank is equipped with a 4.5 m.

1. A tank contains carbon dioxide maintained at 50 C and 0.5
MPa. The tank is equipped with a 4.5 m long pipe. The pipe has in inside
diameter of 1 cm. Find the flow rate in standard cubic feet per minute
corresponding to the specified pressure and temperature. ( CO2
_ = 1.28 and M CO2 = 44).

2. A fully inflated tire has a volume of 15 ft3.
The pressure and temperature of the air in the tire are 65 psia and 75 F,
respectively. At this condition, the air intake needle is depressed for 5
seconds. Treating air as an ideal gas and assuming small changes in the tire
temperature and volume, plot

temperature and volume, plot the mass flow rate of air versus time. Assume a
discharge coefficient of 0.61 and a flow area of 0.01 in2.
