A coolant fluid at 30°C flows over a heated flat plate maintained at a constant temperature of 100°C. The boundary layer temp distribution at a given location on the plate may be approximated as T = 30 + 70exp(-y), where y (in m) is the distance normal to the plate and T is in °C. If the thermal conductivity of the fluid is 1.0 W/mK, the local convective heat transfer (in W/m2K) at that location will be

1.	A coolant fluid at 30°C flows over a heated flat plate maintained at a constant temperature of 100°C. The boundary layer temp distribution at a given location on the plate may be approximated as T = 30 + 70exp(-y), where y (in m) is the distance normal to the plate and T is in °C. If the thermal conductivity of the fluid is 1.0 W/mK, the local convective heat transfer (in W/m2K) at that location will be
