Perfomance analysis of air coolersThe following parameters must be supplied by the userANfinNumber of fins per unit lengthFINODFin outer diameterFINTFin thicknessNrowNumber of tube rowsPl Lateral pitch of the tube arrangementPt Transverse pitch of the tube arrangementTTinTubeside inlet temperatureTainAirside inlet temperatureWairMass flow rate of air.WtubeMass flow rate of tube-side fluidCalculation steps (single phase)1. Estimate the heat duty QLet Cpair = Heat capacity of air at the air inlet temperatureLet Cptube = Heat capacity of tubeside fluid at the tube inlet temperatureLet Cmin = Minimum of WairCpair and WtubeCptube Q = 0.7Cmin (TTin - Tain) (1)2. Estimate the outlet temperaturesTTout = TTin - QCptubeWtube(2a)Taout = Tain - QCpairWair(2b)3. Estimate the airside and tubeside outlet temperatures of each CVBy linear interpolation from the outlet temperatures leaving the air cooler.4. Estimate the pressure drop of each CV- By using the known velocity, temperature at the inlet to each CV 5. Calculate the overall heat transfer coefficient at each CV- Calculate air side heat transfer coefficient- Calculate tubeside heat transfer coefficient- Calculate the overall heat transfer coefficient6. Calculate the airside and tubeside outlet temperatures of each CV- By using the energy balances on each CV 7. Calculate the pressure drop of each CV- By using the momentum and materials balances.8. Repeat steps 5-7 until the temperatures
