For a water flow over a steel surface, the temperature of water at a specific location was found to change with the vertical distance from the surface (y) up to a distance of 0.015 m as T(y) 60 + 20y + tan(y), %3D where temperature is in °C and y is in cm. The surface temperature and ambient temperature was measured as 60°C and 105°C, respectively. The thermal conductivity of steel and water are, respectively, 48 W/m-K and 0.6 W/m-K. What is the local convection coefficient at this location?

Question
Transcribed Image Text:For a water flow over a steel surface, the temperature of water at a specific location was found to change
with the vertical distance from the surface (y) up to a distance of 0.015 m as
T(y) = 60 + 20y + tan(y),
where temperature is in °C and y is in cm. The surface temperature and ambient temperature was
measured as 60°C and 105°C, respectively. The thermal conductivity of steel and water are, respectively,
48 W/m-K and 0.6 W/m-K. What is the local convection coefficient at this location?
