Pressure loss calculation of air ducts and fan pressure selection for process exhaust systems

For exhaust system, the calculation of fan pressure is very important to selection of fan. The matching degree of the design pressure of fans and the system resistance affects the system reliability and efficiency. For process exhaust system, the pressure loss of the waste gas treatment equipment must be considered. With an engineering example, presents the pressure loss calculation of air ducts and fan pressure selection for the process exhaust system.
