Figure shows a proposed device to develop power using energy supplied to the device by heat transfer from a high-temperature industrial process together with a steam input. The figure provides data for steady-state operation. All surfaces are well insulated except for the one at 527°C, through which heat transfer occurs at a rate of 4.21 kW. Ignoring changes in kinetic and potential energy, evaluate the maximum theoretical power that can be developed, in kW.
Air at a pressure of 1 ATM, a temperature of 15° C, and a velocity of 10 m/s flows over a 3 m long flat plate that is heated to a uniform temperature of 140° C. What is the local heat transfer coefficient 3m from the leading edge of the plate?
in a laboratory scientists produce 233th90 from 238u92 by two different processes. in process a a single alpha particle
dry air at 32degreec flows over a wetted water plate of 0.2 m2 area. the average convection coefficient is h 20 wm2
now it is proposed that the liquid water coming out of the separator be used as the heat source in a binary cycle with
At a section where the diameter is 4 in, methane flows with the veloctiy of 50ft/s and a pressure of 85 psia. At a downstream section, where the diameter has increased to 6 in, the pressure is 45 psia. Assuming the flow to be isothermal, compute the ..
Prepare a FMECA analysis on a HDS reactor. All the information about the reactor are attaches including the format required for the FMECA.
an automobile traveling at 90 kmhr rounds a long sweeping curve of radius 250m. the air conditioner is on and the
Answer the following true or false. Explain. (a) A refrigerant at an absolute pressure of 0.8 atm is at a gage pressure of 0.2 atm.
A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the de?ection (thevertical distance between the ?uid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.25 k..

A very rough plate is placed in water. The plate is held constant at a temperature of Ts = 350K, and water flows over the plate at Tinfinity = 300 K. It is desired that the heat lost from the upper surface of the plate be q'' = 1.2 MW/m2. If the plat..
Half a kilogram of nitrogen, initially at 350K and 200Kpa is compressed through a poly tropic process with pv^1.4= constant. If the final temperature is measured to be 400K, find the work in the process.
