Question

a. What units must the constant 0.644 have?
b. What should be the value of the constant when all units are
converted to English units (masses in lbm, lengths in ft, temperatures in oR,
times in h, energies in Btu)?

 

answer asap please

To determine the heat transfer coefficients for forced convection due to laminar flow
outside flat plates, the correlation below is used.
k0.67 (vp)0.5 c0.33
D0.5u0.17
h = 0.644
Where h is in W/m²-K
v is in m/s
p is in kg/m³
Cp is in J/kg-K
D is in m
µ is in Pa-s
