The variation of pressure with density The variation of pressure with density in a thick gas layer is given by P = Cpn, where C and n are constants. Noting that the pressure change across a differential fluid layer of thickness dz in the vertical z-direction is given as dP = – pg dz, obtain […]

The value of Henry’s constant for CO2 The value of Henry’s constant for CO2 gas dissolved in water at 290 K is 12.8 MPa. Consider water exposed to atmospheric air at 100 kPa that contains 3 percent CO2 by volume. Under phase equilibrium conditions, the mole fraction of CO2 gas dissolved in water at 290 […]

The unrestrained expansion of the reactor The unrestrained expansion of the reactor water in Problem 5.48 has a final state in the two-phase region. Find the entropy generated in the process. A water-filled reactor with volume of 1 m3 is at 20 MPa, 360째C and placed inside a containment room as shown in Fig. P5.48. […]

Using EES (or other) software and the relations Using EES (or other) software and the relations given in Table A–32, calculate the one dimensional isentropic compressible-flow functions by varying the upstream Mach number from 1 to 10 in increments of 0.5 for air with k = 1.4. Is this the question you were looking for? […]

The two major forces opposing the motion of a vehicle moving on The two major forces opposing the motion of a vehicle moving on a level road are the rolling resistance of the tires, F and the aerodynamic drag force of the air flowing around the vehicle, Fd, given respectively by Fr fW, Fd= Cd […]

Using EES (or other) software j Using EES (or other) software and the relations given in Table A–33, generate the one dimensional normal shock functions by varying the upstream Mach number from 1 to 10 in increments of 0.5 for air with k = 1.4.   Is this the question you were looking for? If […]

Modern Control Theory Course I have most of the term paper of Active Vehicle Suspension System – it hasn’t simulink). I posted this assignment before but udid not reply me. Now I have matlab code. I need u complete it. I will send some example to help you Is this the question you were looking […]

Using EES (or other) software, determine h Using EES (or other) software, determine the adiabatic flame temperature of CH4(g) when both the fuel and the air enter the combustion chamber at 25째C for the cases of 0, 20, 40, 60, 80, 100, 200, 500, and 1000 percent excess air. Is this the question you were […]

Two different fuels can be used in a heat engine, operating betw Two different fuels can be used in a heat engine, operating between the fuel burning temperature and a low temperature of 350 K. Fuel A burns at 2500 K delivering 52000 kJ/kg and costs $1.75 per kilogram. Fuel B burns at 1700 K, […]

The top part of a water tank is divided The top part of a water tank is divided into two compartments, as shown in Fig. P1–75, now a fluid with an unknown density is poured into one side and the water level rise a certain amount on the other side to compensate for this effect. […]
