If the ECT sensor temperature keeps increasing beyond thermostat opening temperature but the temperature of the radiator hoses is much cooler, what can this indicate

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

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

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
