Carbon dioxide enters an adiabatic nozzle at 8 MPa and 450 K with a low velocity and leaves at 2 MPa and 350 K. Using the generalized enthalpy departure chart, determine the exit velocity of the carbon dioxide
Design a 2:1 rectangular duct and fan system to pull 40000 scfm of air carrying a medium-density dust through an FCD (Final Control Device) with a ?P of 6.0 in. H2O. Assume the duct system must extend 120-feet and has four 90° elbows.
a town requiring 2 cms ofwater has two sources, a local well with 15 g/m^3 of a contaminantand a distant surface water source with 2 g/m^3 of the contaminant.
Determine the purchasing power 3 years from now of an investment of $20,000 today. The investment is earning a market interest rate of 8%, and the inflation rate is 3%.
Assuming unit surface area, find the conductive heat loss through the furnace wall and the temperature at the interface of the fire clay and red brick.
Steam enters a long, horizontal pipe with an inlet diameter of D1 12 cm at 1 MPa and 300°C with a velocity of 2 m/s. Farther downstream, the conditions are 800 kPa and 250°C, and the diameter is D2 = 10 cm. Determine
A film of newtonian liquid folws down the outside surface of avertical cylinder of radius R. the flow is steady, laminar andthe thickness of the film is constant.
Calculate the compression resistance of 200 UC 59.5 column which is 3.6 m high (between lateral supports). Both ends of the stanchion are held effectively in position but only one is also restrained in direction. Use grade 43 steel
Air (m=28.97kg/kmol) is uniformly heated at steady state as it flows through a cylindrical constant area duct. It enters the channel uniformly at 2.5atm, 300K and 80m/s and exits at 1.5atm.
Disinfection by ozone follows first-order kinetics, with a rate constant of 1.2/minute. The town of Obfisquitory wishes to use 4 equal volumes of CFSTR's in series to disinfect 2 million gallons per day (mgd) of water containing 1000 coliforms/L to t..
The total flow then moves to a point W on the traction drive two metres off the ground, and travels through a nine millimetre diameter conduit. Ignoring all friction and minor losses, determine the pressures at points H and W.
an increment of vertical stress of 150kpa compress the sample to a void ratio of1.43. what is the over consolidation ratio of the soil at the unloaded condition.
Heat transfer through the walls and roof is estimated to be 5 40 kJ/hr per degree temperature difference between the inside and outside. a. If the outside temperature in the winter is - 5 C, what power required to drive the heat pum p (kJ/hr
