A. The temperature of an air stream is to be measured, but the thermometer available does not have a sufficiently high range. Accordingly, a dampened cover is placed around the thermometer before it is placed in the air stream. The thermometer reads 32°C. Estimate the true air temperature, assuming that it is dry at atmospheric pressure. B. Dry air at 25°C and atmospheric pressure blows over a 30 cm2 surface of ice at a velocity of 1.5 m/s. Estimate the amount of moisture evaporated per hour, assuming that the block of ice is perfectly insulated except for the surface exposed to the air stream.
