Air initially at rest (M1 = 0) with an initial pressure P1 = 1 atm and temperature T1= 300k flows through a nozzle into a partial vacuum with P2 = 0.2 atm. There is no elevation change. What is the air temperature at the end of the nozzle (T2)?
A mass of 12kg of refrigerant-134a initially exists as a saturated vapor in a piston-cylinder device at 240 kPa. Show the process on a P-v diagram with respect to saturation lines.
If the solenoid is connected in series with a 2.50 Ω resistor and a battery, what is the time constant of the circuit?
What types of engineers (e.g. civil, construction, mechanical, industrial, material science, electrical, etc.) do you think need to be familiar with heat transfer? Why?
An engineer needs to monitor a flow of 20°C gasoline at about 250±25 gal/min through a 4- in-diameter smooth pipe. She can use an orifice plate, a long-radius flow nozzle, or a venturi nozzle, all with 2-in-diameter throats.
