For a particular liquid propellant thrust chamber the following data are given:
Assume the gas composition and temperature to be uniform in the cylindrical chamber section. State any other assumptions that may be needed. Determine the approximate resonance frequencies in the first longitudinal mode, radial mode, and tangential mode.
Propane at 343.15 K (70°C) and 101.33 kPa is compressed isothermally to 1500 kPa. Estimate AH and AS for the process by suitable generalized correlations.
A 30 mol% feed of benzene in toluene is to be distilled in a batch operation. A product having an average composition of 45 mol% benzene is to be produced. Calculate the amount of residue, assuming α = 2.5 and W0 = 100.
Estimate the heat-transfer coefficient for steam condensing on the outside, and on the inside, of a 25 mm o.d., 21 mm i.d. vertical tube 3.66 m long. The steam condensate rate is 0.015 kg/s per tube and condensation takes place at 3 bar. The steam..
