The project is to design a mixing vessel that mixes two liquids described below and cool them down from a high temperature to a lower one. I am unsure about how to go about it, we were told to assume the size of the vessel when calculating.
-House chilled water is available for cooling coming from 6-in dia. chilled water line carrying chilled water at approximate constant 40 degree F temperature. Chilled water pressure in the 6-inch line is 110psig.Chilled water flows through the 6-inch line at 270 gpm.-Vessel is to completely mix both A and B solutions prior to discharge.Resulting mixture is to be cooled to 80 degree F +/-5 degrees prior to exiting the vessel in a single stream.-Solution A- has a 10 gpm +/- flow rate from a 1-in dia. Pipe with temperature 150 deg F +/- 5 degree. Line pressure 20 psig.-Solution B- has a 10 gpm +/- flow rate from a 1-in dia. Pipe with temperature 150 deg F +/- 5 degree. Line pressure 20 psig.
Calculate the over all heat transfer coefficient. Show the calculations in typed form.
Determine the maximum external pull, in each of the four gears, for a tractor with 23-hp, and a max speed of 3.6 mph in 1st gear and a efficiency of 92%. When it is operated over a haul road whose slope is +2.53%.
Given that the average power plant produces 667 MW of electricity per year, there are 492 coal plants in the US, and a solar constant of 1.361 KW/m^2, how large of an area would one need to cover with solar cells to replace our dependence on coal ..
Water is used in a heat exchange to cool 5 kg/s of air from 400 C to 200 C. Calculate (a) the minimum mass flux (kg/s) of the water and (b) the quantity of heat transferred (MJ) to the water each second.
The force of the expanding gases on a 0.02 kg bullet is given by f=f0-f.1*t . Initially stationary at x=0 , the bullet reaches a speed of 1000 kph by the time it exits the gun. f0 = 7000 N and f1=2.9*106 N/s.
a newly designed car has a 9.2 ft wheelbase, is rear wheel drive, and has a center of gravity 18 inches above the the road and 4.3 ft behind the front axle. the car weighs 2450 lb, the mechanical effciency of the drivetrain is 90%, and the wheel r..
determine the pressure head at the nozzle inlet to produce a water jet velocity of 40 ft/s. Neglect the friction loss and assume incompressible flow.
The drinking water needs of an office are met by large water bottles. One end of a .25 in diameter plastic hose is inserted into the bottle placed on a high stand, while the other end with an on/off valve is maintained 2 ft below th bottom of the ..
Cartridges cost $120 each and require 2 weeks to obtain from the vendor. Jill uses (Q,r) policy to control inventory of cartridges. You can assume that there are 50 working weeks in a year.
Susan's 12.0 baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30 degrees above the floor. The tension is a constant 31.0 and the coefficient of friction is 0.210. Use work and energy to find Paul's ..
