Transcribed Image Text:An empirical equation for calculating the inside heat transfer coefficient h; for the
turbulent flow of liquids in a pipe is given by
Where
h₂
0.023G 0.80.670
Dº.2 μ0.47
7C9-33
h₁ = Heat transfer co-efficient (W/m² °C)
G = Mass velocity of the liquid (kg/m² - s)
k = Thermal conductivity of the liquid (W/m - 1 °C)
Cp = Heat capacity of the liquid (J/kg°C)
m = Viscosity of the liquid (kg/m - s)
D = Inside diameter of the pipe (m)
Verify, if the equation is dimensionally consistent.
