One and one-half pounds of water within a piston-cylinder assembly execute a Carnot power cycle. During isothermal expansion, the water is heated at 5008F from saturated liquid to saturated vapor. The vapor then expands adiabatically to a temperature of 1008F and a quality of 70.38%.
(a) Sketch the cycle on p-y coordinates.
(b) Evaluate the heat transfer and work for each process, in Btu.
(c) Evaluate the thermal efficiency.
consider a gas-turbine cycle with two stages of compression and two stages of expansion. the pressure ratio across each
1. Where would you locate the fuel pump in the system so that the system will function correctly? 2.What size tubing would you specify from the pump to the engine?

air flows steadily at low speed through nozzle distance charging to atmosphere. the area at the nozzle inlet is
Determine the mass (in kg) and weight (in N) of the air contained in a typical school classroom whose dimensions are 40 ft x 60 ft x 12 ft. Make suitable assumptions for temperature and pressure given that the classroom is at Penn State in University..
a 3-kg particle is traveling with a velocity of 20 ms inclined an angle of 45 degrees with y-axis. its location can be
A uniform circular disk of mass m = 1 kg and radius R = 0:4m rolls down an incline. Suppose the disk starts rolling from rest. Find the speed of the center-of-mass when the disk is 2m down the inclined plane.

A closed system consisting of 8.25 lb of a gas undergoes a process during which the relation between pressure and volume is pV^n = constant. The process begins with p1 = 18 lbf/in^2 , v1 = 1.25 ft^3 /lb and ends with p2 = 53 lbf/in^2 , v2 = 0.5 ft^3 ..
The 2-kg rod ACB supports the two 4-kg disks at its ends. If both disks are given a clockwise angular velocity (vA)1 = (vB)1 = 5 rad>s while the rod is held stationary and then released, determine the angular velocity of the rod after both disks ha..
