Thermal Principles in Refrigeration Systems by anon_909426932 is a document available to read on EtoBox.
This chapter discusses several thermal principles: 1) Water at 120°C and 250 kPa passing through a pressure-reducing valve will be subcooled liquid. For each kg that enters, 0.0375 kg will leave the separating tank as vapor. 2) For air heated from -10°C to 30°C at a rate of 2.5 kg/s, the rate of heat transfer will be 100 kW. 3) In a venturi flow meter with a manometer deflection of 20 mm, the pressure difference between points A and B is 196.2 Pa, and the airflow rate is 12.32 m3/s. 4) The percentage
