1. According to the equipartition principle, what is the overall energy in J of one mole of water at 1000 K if translational, rotational, and vibrational degrees of freedom are considered?
2. How many equipartition degrees of freedom Nep are present in H2CO
a. when vibrations are not included?
b. when vibrations are included?
Steam at a pressure of 0.08 bar and a quality of 93.2% enters a shell-and-tube heat exchanger where it condenses on the outside of tubes through which cooling water flows, exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing ..

Calculate the Grash of number, the Nusselt number, the convective heat transfer coefficient (h), and the total heat transfer (Q_dot) in ambient air at Tinf = 30C for the following conjurations:
The mechanism of Prob. 2/16 is repeated here. For the conditions () = 40°, T = 150 N, and r = 200 mm, determine the moment about O of the tension T applied by cable AB to point A.
one process follows arrhenius behavior i.e. at a given load the inverse of time to fracture has been shown to increase
Moist air at 45?C and relative humidity 30% (State 1) with another stream of moist air at 20?C and relative humidity 50% (State 2) in an adiabatic duct. Mass flow rate of dry air is 0.8 kg/s at section 1 and 1 kg/s at section 2. The mixed stream (Sta..
