A stream with a flow rate of 65,000 lb/h having thefollowing composition is to be condensed.
The stream will enter the condenser as a saturated vapor at 18 psia, and a maximum pressure drop of 2 psia is specified. The temperature of the condensate leaving the unit should not exceed 180°F. Cooling will be supplied by water from a cooling tower entering at 90°F and 40 psia, with a maximum allowable pressure drop of 10 psia. Use any available software to design a condenser for this service.
Discuss both the reasons for these discrepancies and ssible mechanisms by which such pollutants are formed in an actual engine. In a memorandum, summarize your findings and conclusions.
you are looking for a power unit to run an irrigation pump in your operation. the pump requires 92 horsepower to turn
A welding heat source is capable of transferring 150 Btu/min to the surface of a metal part.
write the temperature of a cooling body as an exponential function of time. Is Newton's Law of Cooling still widely accepted? Are there any substitutes?
heat is to be conducted along a circuit board that has a copper layer on one side. the circuit board is 15 cm long and
water enters a 20ft long cylindrical pipe at a mass flow rate of 20 slugssec. the inside pipe diameter is 8cm. the
A closed rigid, well-insulated tank contains 2 kg of saturated mixture of water at 159kPa. Initially, three-quarters of the mass in the tank is saturated liquid. An electric resistance heater placed in the tank is connected to a 11-V source and curre..
(a) the mass flow rate of steam entering the first stage of the turbine, in lb/h. (b) the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator. (c) the thermal efficiency.
Ways to run cars on water are frequently touted on the Internet. For each of two different such proposals, write a three-page evaluation. In each evaluation, clearly state the claims made in the proposal. Then, using principles of thermodynamics, ..
The angular speed of wheelA is increased from restat a constant rate of 1.6 rad/s2 . Find the time forwheel C to reach the rotational speed of 100rev/min assuming the belt doesn't slip.
Calculate the bulk density, the true porosity, and the volume fraction of the total porosity that consists of closed pores.
The internal diameter is 0.75 times the outer diameter. If the yield stress is 300 MPa and a safety factor of 1.5 is required, determine the minimum inner and outer diameters required according to the Maximum Shear Stress theory (Tresca).
