It is proposed to pump 10,000 kg/h of toluene at 114°C and 1.1 atm abs pressure from the reboiler of a distillation tower to a second distillation unit without cooling the toluene before it enters the pump.
If the friction loss in the line between the reboiler and pump is 7 kN/m2 and the density of toluene is 866 kg/m3, how far above the pump must the liquid level in the reboiler be maintained to give a net positive suction head of 2.5 m?
Calculate the power required to drive the pump if the pump is to elevate the toluene 10 m, the pressure in the second unit is atmospheric, and the friction loss in the discharge line is 35 kN/m2. The velocity in the pump discharge line is 2 m/s. suggest a suitable pump and justify.
water vapor was flowing through the pipeline at 08 mpa pressure and 250 degc temperature. a cylinder-piston mechanism
Taking the average thermal efficiency to be 34 percent, determine the amount of thermal energy rejected by the coal-fired power plants in the United States that year.
A submarine moves steadily through water at a depth of 350m and a speed of 5 m/s. a) find the static pressure p far away from the submarine at the 350m depth 2) find the pressure on the nose of the submarine.(kpa)
Friction between the piston and the cylinder wall can be neglected. For the air, determine the initial and final pressures, in kPa, and the work, in kJ.
natural gas at 70 f and standard atmospheric pressure of 14.7 psi is compressed isentropically to a new absolute
find the temperature of the combustion products of butane when burned in an adiabatic steady flow combustor at 1atm
Find the end pressure with the given information.
A motor has a disk mounted on its shaft. The disk has a diameter of 1 foot and weighs 60 pounds. Starting from rest, the motor rotates at 350 rpm after 5 seconds. If the motor has a 92% efficiency, determine the input power in watts.
The properties of the thermocouple jinction are k=35 w/m.k, p=8500 kg/m^3, and cp = 320 J/kg.k. If the heat transfer coefficient between the thermocouple junction and the gas is 250 w/m^2.K, determine the diameter of the junction.
