Black-body radiation
On the same graph, sketch the energy density of black body radiation u(ω) vs. the frequency ω for the two temperatures T and 2T. (Do not change the axes so that the two curves become identical.) The graph should be large-filling the page, so that details can be seen. Small graphs are not acceptable.
There is no significant heat transfer between the engine and its surroundings, and kinetic and potential energy effects are negligible. For operation at steady state, determine the rate at which power is developed in the absence of internal irreve..
consider a subsonic engine inlet i.e. a diffuser with an inlet area of 2300 in2 and an exitinlet area ratio of 1.44.
How well can you can predict overhead costs on the basis of these variables with a linear regression equation? Why might you be disappointed with the results?
Consider a short cylinder whose top and bottom surfaces are insulated. The cylinder was initially at a uniform temperature of Ti. At time t=0, the cylinder is suddenly subjected to a convection from its side surface to a surrounding fluid at temperat..

juice is extracted from fruits such as apples by compressing and crushing them. based on your knowledge of
at the beginning of the compression stroke in a cold air-standard otto cycle the pressure is 0.1 mpa and the
How fast does water flow from a hole at the bottom of a very wide, 4.6-m-deep storage tank filled with water? Ignore viscosity.
These measurement give an open line impedance of -j50 and a shorted line impedance ofj75. Calculate the characteristic impedance of the line.
Air at a pressure of 6 kN/m2 and a temperature of 300°C flows with a velocity of 10 m/s over a flat plate 0.5 m long. Estimate the cooling rate per unit width of the plate needed to maintain it at a surface temperature of 27°C.
water flowing through a 10-cm-diameter water pipe at a rate of 0.1 m3s. now a diffuser with an outlet diameter of 20
the exhaust nozzle of a jet engine expands air at 300kpa and 200oc adiabatically to 100kpa. determine the air velocity
