Convince yourself that the sum of two TEM waves which have components in opposite directions can produce a TM wave. What are the additional conditions necessary for this to happen?
A rigid tank contains 1.5 kg of water at 120°C and 500 kPa. Now 22 kJ of shaft work is done on the system and the final temperature in the tank is 95°C. If the entropy change of water is zero and the surroundings are at 15°C, determine
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.
Assume Complete combustion write out a stoichmetric equation for 1 mole of an arbitrary alcohol Cx Hy Oz determine the number of moles of air required to burn 1 mole of fuel?
Propane is mixed 20% excess air (propane air mixture is initially at 25 C and 2.0 atm) and combusted at atmospheric pressure. It is assumed that the heat transfer between the chamber and the surroundings is negligible. In addition, you may assume tha..
Assuming that water provides a viscous damping ratio of 0.1, determine the torsional vibratory response of the propeller when the engine induces a harmonic angular displacement of 0.05 sin 314.16t rad at the base (point A) of the propeller shaft.
Assume a diffusion coefficient of 1 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.
Air enters a three-stage gas turbine at 100 kPa and 17 degree Celsius. This system uses a regenerator as well as reheating and inters cooling. The pressure ratio across each compressor is 14.16 (this is 14.16, NOT 14 and 16!); 300 kJ/kg of heat are a..
A flow with a small viscosity but non-zero value may be treated as an inviscid flow if the velocity gradient is not very high. The drag is solely due to the friction between the flow stream and the surface of a body immersed in the fluid. In general,..
package is dropped from the plane which is flying with a constant horizontal velocity of vA = 150 ft/s at a height h = 1500 ft. Determine the radius of curvature of the path of the package just after it is released from plane at A.
contrary to what you might expect a solid steel ball can float on water due to the surface tension effect. determine
Consider the isothermal compression of 0.1 moles of an ideal gas at 300 K from (P1=1.5 bar,V1=2 dm3) to (P2=3 bar,V2=1 dm3). The curve illustrates the internal pressure/volume relationship for the ideal gas at 300 K.If the compression of the gas is c..
A fluid is flowing in a pipe, the pressure drop is 12 psi per 1000 ft. We now double the flow rate, keeping other parameters constant. What is the pressure drop if the new Reynolds’ number is a) 10 and b) 108?
