A blower is being used to force 200 lb of air per hour through a 12-in. inside-diameter tower countercurrent to water flowing at a rate of 6000 lb/h. The tower is packed to a height of 10 ft with 1-in. Berl saddles. The average pressure in the tower is 1 atm, and the temperature is 75°F. The blower-motor combination used at the gas inlet has an overall efficiency of 50 percent. Estimate the power cost per 8000 operating hours for forcing the air through the packing if the cost of power is $0.08 per kilowatt hour.
Calculate the mass feed rate of hydrogen (kg/s) required to produce 4 x 106 metric tons of ethane per year, assuming the reaction goes to completion and that the process operates for 24 hours a day and 300 days a year. (20.6 kg H2/s)
In terms of heat treatment and the development of microstructure, what are two major limitations of the iron-iron carbide phase diagram?
Develop a mathematical model that describes how the pressure in the tank varies with time.
Calculate the line voltage at the secondary terminals of the transformer if the load is disconnected from the transformer. Assume that the input voltage to the transformer remains unchanged. Neglect core loss and magnetizing current
Here you compare the value of H when you use actual data (steam tables) and when you assume ideal gas. Reference means H = 0. State all reasonable assumptions. Vapor-liquid phase partitioning is involved.
Water (1.25 kg/s) is to be heated from a pipeline temperature of 15°C to 85°C using superheated steam (13.75 kg/s) at 550°C and 3 MPa in a steady-state process to produce 15 kg/s of heated water. The heating is to be done in a mixing tank by directly..
Kyoto box is a simple solar oven used extensively in Africa. Assuming a square box with four reflectors of L = 75 cm, on a sunny day with direct sunlight from the zenith, what is the optimum angle ?? What is the total solar power received by the b..
(1) Determine the mass and the temperature of the steam in an insulated piston-cylinder arrangement if sufficient steam is admitted to displace the piston by one cubic foot. The cylinder originally is empty, and the piston main- tains a constant pres..
What is the settling velocity in still air of a particle that is 40 µm in diameter and spherical? The particle has a density of 1400 Kg/m3. Use a density of 1.2 Kg/m3 and a viscosity
When burnt , the flue gas issuing out of the furnace at 545 oc analyses on dry basis as CO2 =14.5 % , O2 = 4.7%, N2 = 80.8 % , Other relevant data are- Gross C.V. of coal =28000 kj /kg , ambient temperature = 15oc
QUESTION - 1 . The rate of a liquid phase reaction of the type ,A+B --àproducts is found to be independent of concentration of A and B and equal to 1 KMOL/m3 ( min) at 300 ok
