Refrigerant 134a enters a horizontal pipe operating at steady state at 40 oC, 300 kPa and a velocity of 40 m/s. At the exit, the temperature is 50 oC and the pressure is 240 kPa. The pipe diameter is 0.04 m. Determine

a) the mass flow rate of the refrigerant, in kg/s

b) the velocity at the exit, in m/s

c) the rate of heat transfer between the pipe and its surroundings, in kW

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
