The experimental data shown tabulated were obtained by passing n-butyl alcohol at a bulk temperature of 15°C over a heated flat plate (0.3-m-long, 0.9-m-wide, surface temperature of 60°C). Correlate the experimental data using appropriate dimensionless numbers and compare the line which best fits the data with Equation 5.38.
GIVEN
n-butyl alcohol flowing over a heated flat plate
Bulk temperature (Tb) = 15°C
Plate surface temperature (Tp) = 60°C
Plate length (L) = 0.3 m
Plate width (w) = 0.9 m
The experimental data given above
FIND
(a) Correlate the data by appropriate dimensionless numbers
(b) Compare line which best fits the data with Equation 5.38
ASSUMPTIONS
Steady state
Alcohol flows parallel to the length of the plate
Plate temperature is uniform
