Cooling water is used to condense propane vapor that enters the condenser saturated at 200 psia. The condensate is a saturated liquid at the same pressure. The cooling water enters the condenser at 70°F and its temperature cannot increase more than 25°F as it passes through the condenser. If the maximum flow rate of the cooling water is 60,000 lbm/h and its heat capacity is constant at 1 Btu/(lbm·°F), estimate the maximum flow rate of propane (SCFH) vapor to the condenser.
When making a plot with the Claussius Clapeyron equation, the enthalpy of vaporization can be calculated from the slope of the line of lnP vs 1/T.
Sodium atoms(Na) emit light with a wavelength(λ) of 330 nano meters when an electron moves from a state of 4 p orbital to a state of 3 s orbital now you just need to determine the energy difference between the orbitals.
