QUESTION 1
a) Two resistances of 812 and 1222 are connected in parallel. These resistances further connected in
series with a 5.212 resistance. If current through the 5.292 resistance is 1.2 amperes, what will be
the current through the 812 and 12 respectively, the total resistance of the circuit and voltage
across the whole circuit?

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i.e., a violation of one statement leads to the violatio the other statement)

Acircular pipe of 30mm outside diameter is placed in an airstream at 30 c and latm pressure. the air moves in cross flow over the pipe at 20 m/s, while the outer surface of the pipe is maintained at 110 c. what is the drag force exerted on the pipe per unit length? what is the rate of heat transfer from the pipe per unit length?

Ir at sea level and 30°c and 50% relative humidity flows at a rate of 1 kg/s through a cooling coil that has an apparatus dewpoint of 10°c. the air leaves the coil at 15°c. determine the following: 3.1)- relative humidity of the air leaving the coil; 3.2)- moisture content of the air leaving the coil; 3.3)- sensible heat factor; 3.4)- total heat transfer rate; 3.5)- sensible heat transfer rate 3.6)- latent heat transfer rate
