An electrically charged resistance wire has a diameter of 2mm and a resistance of 0.10ohm per foot of wire. The thermal conductivity of the wire is 10btu/hr sq ft. At a current oof 100amp, calculate the temperature difference between the center of the wire at steady rate

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
