Using the psychrometric chart Appendix Chart C-1, determine the vapor pressure of water in air at 80ºF, 40% relative humidity. Also determine the humidity ratio, the enthalpy, the dew point temperature and the wet bulb temperature.
What will be an ideal response?
Air at 20°C flows at 1 m/s between two parallel flat plates spaced 5 cm apart. Estimate the distance from the entrance to the point at which the hydrodynamic boundary layers meet.
GIVEN
Air flows between two parallel flat plates
Air speed (U?) = 1 m/s
Distance between the plates (D) = 5 cm = 0.05 m
Air temperature = 20°C
FIND
The distance from the entrance (X1) where the boundary layers meet
ASSUMPTIONS
Steady state
Laminar flow
