Which stroke of the four stroke cycle is shown in the above figure.
a. compression
b. intake
c. power
d. exhaust

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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 quality is zero at a)-the saturated vapour state b)-the saturated liquid state c)-the saturated liquid-vapour mixture state d)-none of the states in the other answers
