Applied Heat past Examination Questions 1. An Ammonia refrigerator is to produce 2 tonnes of ice per day at -4°C from water at 20°C. if the temperature range in the compressor is between 25°C and -6°C, Calculate the horsepower required to derive the compressor. Latent Heat of ice = 80 kcal/kg, and specific heat of ice= 0. 5 2. A compressor draws 42. 5 m3 […]

Vapor Pressure and Heat of Vaporization Introduction Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid, new gas molecules exert pressure in the sealed container, while […]

The objective of this laboratory experiment is to investigate the radiation laws (Lambert’s Distance, Cosine Law and Stefan-Boltzmann Law) using thermal and optical radiation. This experiment was carried out with the assistance of the Thermal Radiation Apparatus which consists of a heat source (that provides the heat for the verification of the Stefan-Boltzmann Law), a thermopile (that assists in detecting the temperature), a luxmeter (that […]
