Methane gas (CH4) enters a compressor at 298 K, 1 bar and exits at 2 bar and temperature T. Employing the ideal gas model, determine T, in K, if there is no change in specific entropy from inlet to exit.
The specific heat C of pure copper is given at 100, 200, 400, 600, and 800 K as 252, 356, 397, 417, and 433 J/kg K. Employ Lagrange interpolations to compute the values at 300 K and 500 K. Also, compute the extrapolated value at 1000 K and compare it..
a remote sensing satellite is deployed in a circular sun-synchronous orbit with inclination 96.85deg. a. calculate
A US Department of Energy article states that a leak of one drip of hot water per second can cost $1.00 per month. Making reasonable assumptions about drop size and unit cost of energy, determine if this claim is reasonable.
the acceleration of gravity g as a function of elevation z above sea level is given by g 32.17 - 3.32x10-6 z where g
A batter hits the baseball A with an initial velocity of v0 = 103 ft/sec directly toward fielder B at an angle of 34° to the horizontal; the initial position of the ball is 2.0 ft above ground level. Fielder B requires 0.43 sec to judge where the bal..

Find the heat flux (the rate of heat transfer divided by the surface area through which conduction occurs) through a 2 cm thick asphalt shingle roof on a cold winter morning. The shingles have a thermal conductivity of 0.75 W/m-K. The temperature ins..
A 3.31 ft3 rigid tank contains saturated refrigerant-134 at 100psi. Initially, 14 percent of the volume is occupied by liquid and the rest by vapor. A valve at the top of the tank is now opened, and vapor is allowed to escape slowly from the tank. He..

two steel shafts are made of cold-drawn steels having ultimate tensile strengths of 185 kpsi and 240 kpsi respectively.
The length of the cable between points A and B is 87 m, and the effective cable mass is 2 kg /m when the buoyancy of the cable is accounted for. Determine the tensions at both A and B.
