You are conducting a series of flow experiments in order to investigate flow across a horizontal flat plate. When water at 51.9°C flows across a flat plate, the distance from the front edge of the plate to where the transition from laminar to turbulent flow occurs is determined to be 314mm. 1. What is the bulk velocity of the water flowing over the plate? 2. If the experiment is done with Refrigerant-22 instead of water and the same distance from the edge is measured, what would the bulk velocity be? 3. Compare the velocity and thermal boundary layer thickness at the laminar/turbulent transition point of the two cases above and comment on your finding.

Question

100%

You are conducting a series of flow experiments in order to investigate flow across a horizontal flat
plate. When water at 51.9°C flows across a flat plate, the distance from the front edge of the plate to
where the transition from laminar to turbulent flow occurs is determined to be 314mm.
1. What is the bulk velocity of the water flowing over the plate?
2. If the experiment is done with Refrigerant-22 instead of water and the same distance from the edge
is measured, what would the bulk velocity be?
3. Compare the velocity and thermal boundary layer thickness at the laminar/turbulent transition
point of the two cases above and comment on your finding.
4. Based on the average convective heat transfer coefficient up to the laminar/turbulent transition
distance, which fluid would yield a higher heat transfer rate under the specified conditions?

Wind flows over a flat plate of length L = 25 mm and width W = 8 mm. The plate is maintained at a constant temperature of 32 °C on both sides. using an electric heater generating heat at a rate of Q = 0.5 W which is dissipated to air from both sides of the plate. Consider the temperature of the wind/air as 20 °C and assume that the wind speed does not exceed 100 m/s. The properties of air at this temperature are given as; specific heat capacity Cp = 1.005 kJ/kg-K, thermal conductivity k = 0.0253 W/m-K, Density p = 1.19 kg/m³, and kinematic viscosity v = 1.522 x 10 5 m²/s.
