Carbon dioxide gas enters a pipe at 3 MPa and 500 K at a rate of 2 kg/s. CO2 is cooled at constant pressure as it flows in the pipe and the temperature of CO2 drops to 450 K at the exit. Determine the volumetric flow rate and the density of carbon dioxide at the inlet and the volumetric flow rate at the exit of the pipe using (a) the ideal gas equation of state and (b) the generalized compressibility chart. Also, determine (c) the error involved in the first case.
consider refrigerant r-134a flowing in a smooth horizontal 10-mm-inner-diameter tube of wall thickness 2 mm. the
The x and y components of velocity for a two-dimensional flow are u = 5y ft/s and v = 4 ft/s, where y is in feet. Determine the equation for the streamlines. Use C as constant. Round all numbers in answer to 3 significant digits.
A brass rod is stress-free at room temperature (20 degrees Celsius). It is then heated up but prevented from lengthening at its ends by external forces. At what temperature does the stress in the rod reach 172 MPa? Assume the modulus of elasticity is..
Refrigerant 134a exits a heat exchanger through .75-in - diameter tubing with a mass flow rate of .9 lb/s. The temperature and quality of the refrigerant are -15 Fahrenheit and .05, respectively. Determine the velocity of the refrigerant, in m/s.
