For a Digital Muti-meter when set to the Diode Test, It will indicate continuity when the RED lead is connected to the Anode of a known good Diode and the black lead is connected to the Cathode (will show Forward voltage drop). When the leads are Reversed, there is no continuity indicated. With this knowledge, you know test an unknown transistor whose terminals are numbered #1,#2 and #3 and obtained the following result:

Red #1 #1 #2 #2 #3 #3
Black #2 #3 #1 #3 #1 #2
Result No Continuity, Continuity, No Continuity, Continuity, No Continuity, No Continuity

a) Is the Transistor Good or Bad?
b) Which terminals #1, #2 or #3 is the Base?
c) Is it PNP or NPN?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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.
