The discussion will be limited to engines operating on biomass or a fuel derived from biomass, since biomass is the main indigenous fuel source in most developing countries. Then all the losses head up: like valves tension losses, filters, tubing and when used in combination with a tank, the resistance e.g. When heat capacity ratio (k) is meant, is it Cp/Cv or Cp/(Cp-R) (i.e., an ideal gas heat capacity ratio)? Did you make a linear best fit in excel in between the dependent variable k and independent variable y and arrived at the eqn.? Method 2: natural gas. This is because a gas engine actually produces power through its own combustion, while electric motors draw their power from an external system. Equations 1 and 2 are equally correct theoretically. if someone could explain to me what all the letters stood for it would be a great help, Adamson: For Polytropic process . Online Pump Calculator - SI-units. incorporating ‘real’ values of ‘k’ (from HYSYS) into the API equations for relief valve sizing can over-estimate the capacity of a given orifice. The unit of ke is m2/s2which is equivalentto Joule/kg. It should include convection and radiation heat losses. Dr. The control volumes provide the pressure, temperature, and specific enthalpy for the compressor to calculate … Though less convenient, combustor temperature rise is a better gauge of the cycle’s ability to deliver power. Can the polytropic efficiency of compression be greater than unity,when n is less than k (i.e 1
