Adevice compresses isothermally 1 lbmol/hr of ideal gas at 1000r and releases 3000 btu of heat, which is transferred to another 1 lbmol/hr of ideal gas, which expands, isothermally from 2.72 atm to 1 atm. is it possible to have such a device? consider the process to be reversible.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
