Question
A beaker contains a fluid of density ρ kg / m3, specific heat S J / kgoC and viscosity η. The beaker is filled upto height h. To estimate the rate of heat transfer per unit area (Q / A) by convection when
beaker is put on a hot plate, a student proposes that it should depend on η
and
when ᐃθ (in oC) is the difference in the temperature between the bottom and top of the fluid. In that
situation the correct option for (Q / A) is :

Options
A.
B.
C.
D.
Solution
MT-3 = [ML-1T-1]a [LT-2]b [M-1L2T2 ]c
MT-3 = [Ma-c L-a+b+2c T-a-2b+2c]
