A diesel engine draws in air at the inlet at 95kPa pressure, 300K temperature. The engine has a compression ratio of 20:1. The heat released during combustion is 1300 kJ/kg. Using the cold air standard assumptions, please calculate: a) The temperature after combustion.
b) The cycle efficiency
c) The mean effective pressure for the cycle
d) The cutoff ratio for the cycle

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
