Q7 -سيف مهند. 2- شهد رحيم. 3-صادق امين 3- طه أحمد 4- عباس أحمد فهد A gas expanded adiabatically from the initial pressure and temperature of 950 kN/m²and 600 °C respectively to a pressure of 100 kN/m? .The gas is then heated at constant volume, then the gas was isothermally compressed to the initial conditions. Take y= 1.5.
Thermodynamics
A piston-cylinder device initially contains 0.4 m^3 of saturated water vapor at a pressure of 200 kPa. At this time, a linear spring (K = 150 N/m) is touching the piston, but exerts no force upon it. Heat is now transferred to the water vapor for 30 minutes through a resistive heater having a current of 10 amperes. The pressure and volume rise to 300 kPa and 0.6 m^3 while the system lost 10 kJ of heat during this process. Determine the voltage of the resistive heater and draw the provess on a P-v diagram with respect to saturation lines. Show detailed calculations and specify any required values found on thermodynamic tables.
