A pipe with insulation: For the same thickness and type of insulation, the thermal resistance of the insulation 1. Decreases with decreasing radius of the pipe
2. Increases with decreasing radius of the pipe
3. Does not change with decreasing radius of the pipe
4. Could either increase or decrease with decreasing radius of the pipe

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
