A simple method of determining the available short-circuit currents (also referred to as fault current) at various distances from a given location is the method. a. point-to-fault
b. point-to-ground
c. point-to-point
d. point-to-phase

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.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
