½ kg of a liquid-vapor water mixture in a rigid tank initially at 2 bar is heated by 120V heater for 5 minutes until it becomes a saturated vapor at 4 bar. Changes in kinetic and potential energies can be ignored. Determine:
a) The volume of the
b) The initial quality of the mixture
c) The change in internal energy
d) The current of the heater assuming all of the power consumed by the heater is transferred as heat to the mixture

Use the function for thermodata evaluation in the matlab toolbox to compute species thermodata and kp of the reaction 2CO2= 2CO + O2 for T=3000K. Solve the equilibrium concentration manually by solving the progress variable first (Show the procedure)..
A submarine cruising 40 m below the free surface of seawater whose density is 1025 kg/m3. Calculate the increase in the pressure exerted on the submarine when it dives to a depth of 150 m below the free surface in kPa.
A piston-cylinder assembly contains 2 lbm of water, initially at 100 lbf/in.2 and 400o F. The water undergoes two processes in series: a constant pressure process followed by a constant volume process. At the end of the constant volume process, the t..
