A stagnant liquid film of 0.4 mm thickness is held between two parallel plates. The top plate is maintained at 400C and the bottom plate is maintained at 300C. If

the thermal conductivity of the liquid is 0.14 W/(m K), then the steady state heat flux ( W/m²) assuming one-dimensional heat transfer is
