1.A frictionless piston-cylinder contains 2kg of nitrogen at 100 kPa absolute and 300 deg K. The system is compressed polyprotically at a 1.4 exponent (n) until the nitrogen reaches a final temperature of 360 deg K.
Plot this process on a P-V diagram and a P-T diagram.
2.The solids in a specimen have a specific gravity of 2.65. If the oven-dry mass of the specimen is 25kg, what is the volume of the solids in it?
On a single graph, show how the Gibbs energies of each of these phases vary with temperature between - 20 C and 150 C for a constant pressure of 80 kPa. You can start your computations at the triple point
a horizontal cylindrical tank 4 ft in diameter and 10 ft long is full of water. find the work done in pumping the water to a point 4 above the top of the tank.
The steel rails of a continuous, straight railroad track are each 60 ft long and are laid with spaces between their ends of 0.25 inches at 70 degrees F. At what temperature will the rails touch end to end
Compute the energy loss in a 90 degree bend in a steel tube used for a fluid power system. The tube has a 0.5 inch outside diameter and a wall thickness of 0.065 inches. The mean bend radius is 2.00 in. The flow rate of hydraulic oil is 3.5 gal/mi..
Calculate the total head loss for water (25°C) flowing at 100 m3/hr as shown in the following figure. The total flow length is 250 meters and the pipe is 15-cm diameter cast iron pipe
Using the following assumptions, determine the solids retention time, the cell wastage flow rate, and the return sludge flow ratefor the Jambalaya shrimp processing plant WWTP
You are assined the task of process design for a fixed-bed carbon adsorber system. You are given the following data: the inlet airstream flows at 5000 acfm (at 95 degrees F and 1 atm) and contains .2% n-pentane by volume
Assume the plane is flying at an altitude of 32,810 ft (10 km), where the temperature is -8 C and the pressure is 250 mb. The Pitot-static tube measures a piezometric pressure difference corresponding to 1.206 psi. What is the airspeed in both m/s..
Write a brief description (1-3 paragraphs) of the Saint Venant equations (words only, no equations) comparing them to the Navier-Stokes equations, emphasizing the ASSUMPTIONS on which they are based.
A discharge of 2,200 ft^3/sec flows in a trapezoidal channel at a normal depth of 8.0 ft. The channel has a slope of 0.01, a 12-ft bottom width, and side slopes of 1:1 (H:V). Determine the manning coefficient of channel roughness
Determine the minimum length of a crest vertical curve if the grades are +4% and -2%, Design speed is 70 mi/h. State assumptions used in solving this problem.
Steam at 550 degree Celsius, 17.5 MPa enters the high-pressure turbine of an ideal reheat Rankine cycle. The steam exits the high-pressure turbine at 2 MPa, is reheated to 550 degree Celsius, and then expanded through a low-pressure turbine
