For a given power source of 300 kW electrical output, a propellant mass of 6000 lbm, α = 450 W/kg, and a payload of 4000 lbm, determine the thrust, ideal velocity increment, and duration of powered flight for the following three cases:
air at 4mpa and 3000c enters a will insulated turbine operating at steady state with negligible velocity. the air
Draw a block diagram for the controlsystem.
what is the discharge temperature and what is the work output per mole of C02? Assume CO2 to be an ideal gas at these conditions.
Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0C (called the molar heat capacity of silver). c. It takes 1.25 kJ of energy to heat a sample of pure silver from 12.0C to 15.2C. Calculate the mass of the sample of silv..
The 50-turn coil in the configuration of Figure P12.1.3 is rotated at a constant speed of 300 r/min. The axis of rotation is perpendicular to a uniform magnetic flux density of 0.1 T. The loop has width w = 10 cm and length l = 1 m
A vapour stream that is 65 mole% styrene and 35 mole% toluene is in equilibrium with a liquid mixture of the same two species. The pressure in the system is 20 kPa. Use Raoult's law to estimate the composition of the liquid and the system temperat..
5. A patient is placed on a kidney dialysis unit three times a week. The dialyzer has a membrane area of 1 m2 and is operated in a countercurrent mode. The blood flow rate is 200 ml/min and the dialysate flow rate is 500 ml/min. Membrane permeability..
The pressure is adjusted so that 75% of the mixture is vapor while the temperature remains at 55 °C. Determine the pressure and the compositions of the two phases.
For a reversible exothermic elementary catalytic reaction of the type A B, what is the optimum operating reaction temperature at a conversion level , xa = 0.8 given- K1 = exp ( 10 -5000/T) K2 = exp ( 40 - 15000 /T) and maximum allowable temperatu..
