In the proof that I have studied, there is a Isothermal cavity that behaves as a black body. there is another small opaque body inside the cavity at the same temperature with emissivity e, absorptivity a and area s. now the irradiation on the small body is Eb = σ times T raised to 4. now the...
If i have a shaft & I'm applying a driving torque D at one end & at other end there is resisting torque R due to bearing friction, etc. Then if D>R, i have net torque = moment of inertia times angular acceleration. Since the ang. accln is constant with respect to time, will the ang. speed of...
Hello, I am a student of mechanical engineering. I am considering a research career in my field. The reason I'm attracted to research is I want to be doing something new everyday not a regular job routine. Also I have a fiercely independent nature and i hate to be ordered around. I like to do...
I read it in some books and many places on the net that a partial vacuum is created by virtue of great difference in specific volumes of steam & the condensed water. Is it wrong?
I am a 2nd year mech engg student. I have a basic doubt in condensers. The steam from turbine exhaust enters the condenser & gets condensed during which its specific volume decreases resulting in formation of partial vacuum. Now according to rankine cycle the process in a condenser is a isobaric...
