1. Gaseous propane (C3H8) at 77°F, 1 atm enters a reactor operating at steady state and burns with the theoretical amount of air entering separately at 240°F, 1 atm. An equilibrium mixture of CO2, CO, H2O(g) O2, and N2 exits at 3140°F, 1 atm. Determine the heat transfer between the reactor and its surroundings, in Btu per lbmol of propane entering. Neglect kinetic and potential energy effects.
2. One kmol of CO2 in a piston-cylinder assembly, initially at temperature T and 1 atm, is heated at constant pressure until a final state is attained consisting of an equilibrium mixture of CO2, CO, and O2 in which the amount of CO2 present is 0.422 kmol. Determine the heat transfer and the work, each in kJ, ifT is (a) 298 K, (b) 400 K.
determine the work required to compress steam isentropically from 100 kpa to 1 mpa assuming that the steam exists as a

two kilograms of water fills a 0.1 m3 rigid tank the volume will not change at an initial pressure of 2mpa. the
Saturated isobutane vapor at 320 K is contained in a piston-cylinder assembly. It is expanded to 3 bar by a reversible isothermal process. At 320 K, the vapor pressure of isobutane is 6.243 bar. Using the truncated virial equation of state, i.e. with..
A geothermal pump is used to pump brine whose density is 1050 kg/m3 at a rate of 0.3 m3/s from a depth of 200 m, For a pump efficiency of 74 percent, determine the required power input to the pump.
what is the reason for the system? -to increase the air pressure from 100 to 1200 kpa design uses dual compressors to
air enters the compressor of an ideal closed air-standard brayton cycle at 100kpa with a volumetric flow rate of 5m3s.
a steam turbine operates with 1.6 mpa and 350o c steam at its inlet and saturated vapor at 30o c at its exit. determine
Apply the separation of variables method to the Schrodinger equation for the hydrogen atom in spherical coordinates. The solutions for the three ordinary differential equations obtained in step 1 should be found in a Math textbook. Please make sure t..
Compute the weight percent sulphur that must be added to completely crosslink an alternating chloroprene-acrylonitrile copolymer, assuming that 6 sulphur atoms participate in each crosslink.
steam enters a turbine at 9 mpa and 500 celcius with a velocity of 50 ms and leaves at 20 kpa with a quality of 90
Estimate the mass of the gas in the tank in kg assuming the gas behaves as an ideal gas. If the gas warms up to 35 deg C as it sits in the sun all day, what would the pressure rise to?
