Felix has placed some copper wire (where the official looked up inferred absolute temperature is 234.5 celsius) 28 gauge wire in a freezer at 15.3 degrees fahrenheit. he measures the resistance of the cold wire to be 15.3 ohms. what is the length of the wire in units of feet?

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

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