a) Calculate overall gain Gv when switch goes to 1. Please round to the nearest two decimal places. (b) If the switch goes to 2 the amplitude of the output vo is halved (half the original value), in this case what is the value of RS

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

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody
