A system executes a power cycle while receiving 1050 kJ by heat transfer at a temperature of 525 K and discharging 700 kJ by heat transfer at 350 K. There are no other heat transfers.
It is now cooled at constant volume to 200 deg C. This process is followed by an isothermal process ending at the saturated liquid state. Determine the total heat transfer required in kJ.
A heat pump with a COP of 3.0 is used to heat air contained in a 1205.4m^3 of well-insulated, rigid tank. Initially the pressure and the temperature inside the gas tank are 100 kPa and 7 degrees Celsius, respectively.
Knowing that the constant of eachspring is 2 kN/m, determine (a) the velocity of the block after ithas moved down 50 mm, (b) the maximum velocity achieved by theblock.
A nozzle with inlet area of 800 cm2 and inlet steam velocity is 10m/s. The steam pressure is 800kPa and temperature is 400C at the inlet and the pressure and temperature change into 200kPa and 300°C at the outlet.
A mixing chamber steadily mixes a hot water stream at 80°C and 0.5kg/s rate with a cold water stream at 20°C. If the leaving mixture is at 42°C and mixing happens at 250kPa, determine the mass flow rate of the cold water stream.
More heat is transferred to the air until the temperature becomes 1000 K. Show the processes on a P-V diagram and calculate the following The final pressure in the cylinder.
A square plate of edge length 12.0 cm and negligible thickness has a total charge of 5.80 x 10-6 C. Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.50 mm from the center) by assuming that t
