A system consisting of 1 kg of water undergoes a cycle composed of the following processes:
Process 1-2: constant-volume heating from p1 = 500 kPa, T1 = 160°C to p2 = 1000 kPa.
Process 2-3: constant-pressure process to saturated vapor.
Process 3-4: constant-volume cooling.
Process 4-1: isothermal expansion with Q41 = 815.8 kJ.
Neglecting kinetic and potential energies, determine the work and heat transfer for each process, all in kJ.
Determine the internal normal force, shear force, and moment at point C in the simply supported beam. Point C is located just to the right of the 1500 couple moment.
the space between two 17-in.-long concentric cylinders is filled with glycerin viscosity 8.5 times 10-3 lbmiddotsft2.
A bar made from a material with a elasticity of 122 GPa and with a cross sectional area of 17 cm2 is attached at point C to a spring with a constant k of 322 MN/m. The lengths L1 and L2 are 0.1 m and 0.4 m, respectively. If the force has a magnitude ..
an actual refrigerator absorbs 500 kj of heat from a sink at 250 k and reject 660 kj of heat to environment at 300 k.
argon gas initially at 1 bar 100 k undergoes a polytropic process with n k to a final pressure of 15.59 bar. the work
A vortex tube is used to separate an ideal gas at 10 bar and 375 K such that half the gas is collected in a cool stream at 1 bar and 255 K and the other half becomes a hot stream at 1 bar and 495 K. Assuming the process is adiabatic: is this process ..
