Q1: At a constant velocity of 20 m/s, air passes across a flat plate with ambient pressure
and temperature of 20 kPa and 20°C. At a distance of 7.5 cm from the leading edge, the
plate is heated to a constant temperature of 75°C. How much heat is transferred overall
from the leading edge to a location 35 cm from the leading edge?

Q2: The critical Reynolds number for flow over a flat plate in a particular application is
10°. This critical Reynolds number and an isothermal plate temperature of 400 K are
encountered by air flowing across it at 1 atm, 300 K, and 10 m/s. At the end of the plate,
the Reynolds number is 5 x 106. What will average heat transfer coefficient be for this
system? What is the length of the plate? What is the plate's loss of heat?
