1. Homework Statement
Let a and b be two given orthonormal vectors around a fixed point O. The motion of a continuum is defined by the following velocity field:
v(M) = \alpha \vec{a} (\vec{b} . \vec{OM})
where \alpha is a known...

I have been trying this question all day:
hot gases exit the gas generator of a turbojet engine at a temperature of 1027 C and a pressure of 10 bar. If the mass flowrate of the exhaust gas is 10 kg/s, determine the thrust developed by the engine when the aircraft is a) stationary and b)...
oh no I think I understand now.
It is like comparing 2 engines operating at room temp, one with a higher Th (Th2) than the other (Th1). If you use the lower Th than the max amount of work potential lost is the difference bewteen the max amount of work for the engine at Th2 and Th1.
Thanks. I see that the heat transfer to the environment is important
So Wmax2 is the heat transferred from the hottest resevoir to the environment and Wmax1 is the heat transferred from the 350C resevoir to the enviroment. The difference between these is the maximum amount of heat that could be...
Hi I am studying this topic at the moment and came across this question but cannot solve it. Any help would be much appreciated.
Heat is transferred from a resevoir at 1200C to a second resevoir at 350C at a rate of 500 KJ/s.
Calculate the rate at which work potential is destroyed during...
i have an exam in these kind of questions in a few days so i was pracitsing a a few problems but I can't do them!
Any help would be appreciated.
Calculate the Fourier series for f(x) when f(x) = 0, on -pi <= x <= 0, and f(x) = coshx, on 0 <= x <= pi.
and show that SUM (from n=1 to...
