operating practices during the testing phase.To successfully accomplish the task all students were introduced to the salient features of thepump experimental system and the associated components. The energy equation was employedto explain the dependency of the flow rate Q upon the pressure head (H) added by the pump. Inideal conditions this imbalance is the pressure difference (∆P) between the system inlet andoutlet. So that the pressure head obtained by a pump is directly dependent upon the power (P)supplied to the pump. Students were then explained how various combinations of the appropriatepump parameters such as flow rate (Q), head (H), Power (P), Speed (N - rpm), and the impellerdiameter (D) yield affinity laws3, 4. It was further shown how

theprojectile. Typically the comparator was set to switch at approximately 2.5 volts. The output ofthe analog comparator is open collector; this open collector output is connected to the +5voltsupply through a 10k ohm resistor. The output of the first analog comparator is used as a startsignal for the counter. The first sensor pair executes the start, and the second pair executes thestop. This start / stop is accomplished by the use of a J-K flip-flop. The start sensor wasconnected to the J input of the flip-flop and the stop sensor was connected to the K input. Whenthe start sensor was triggered high it sends the J input high and sets the flip-flop output 'Q' to alogic high. When the flip-flop's output is high the 1 MHz clock signal is then passed

A conditional check was included to ensure thepressure does not go below zero. Currently it is assumed that the valve is isenthalpic (constantenthalpy) and that the exit temperature is the saturation temperature at the exit pressure.There was not an easy way to determine the power out of the Variac as a function of controlknob position (%Variac). Therefore, the power delivered ( Q% input ) is computed from the knob Page 11.461.7position and a power per % knob position value. The

As illustrated inTable 3, thermal conductance is used todescribe the heat-retaining capabilities ofbiological species, particularly hair- and fur-bearing animals.

professors go through it enough timesnot to be bothered by it anymore. For example, one of the most common thermodynamic jargon terms is “adiabatic,”coined in 1859 by William John Macquorn Rankine. He used it to mean “no heat is lost orgained by the system.” It is a word (like many of the thermodynamic jargon terms) that is really •a number. Numerically it means Q = 0 (and Q = 0). A modern English term for it is“insulated.” Students quickly understand what “insulated” means, but struggle throughout thesubject interpreting “adiabatic.” We could just say, “there is no heat transfer,” or “the system isinsulated,” but we don’t, we say “adiabatic system,” as we were taught. However, “adiabatic”really
