![21. An empirical equation for calculating the inside heat transfer coefficient,
hi for the turbulent flow of liquids in a pipe is given by:
h₂ =
0.023 GO.S KO.67 Cp0.33
D0.2 μ0.47
where h₁ = heat transfer coefficient, Btu/(hr)(ft)2(°F)
G = mass velocity of the liquid, lbm/(hr)(ft)²
K = thermal conductivity of the liquid, Btu/(hr)(ft)(°F)
Cp = heat capacity of the liquid, Btu/(lbm)(°F)
m = Viscosity of the liquid, lbm/(ft)(hr)
D = inside diameter of the pipe, (ft)
What will be the value of the constant, given as 0.023, if all the
variables in the equation are inserted in Sl units and hi is in Sl units.
a. 0.417
c. 0.011
b. 0.023
d. 0.335](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1c6167d3-d982-43c8-91cd-03b4f95caa99%2F856b2a5c-d835-406d-be9e-e96ce2c039ed%2Fxrfsq3c_processed.jpeg&w=3840&q=75)
