Consider the heating of an incompressible fluid with velocity Um inside a thin - walled tube. The diameter of the tube is D. Heating is in the hydrodynamically and thermally developed region and the flow is laminar.
A compressive force of 100kN is applied to one side, while a tension force of 200 kN is applied to a second side. What is the change in length in the unloaded direction?
Find the force exerted on an electron at this point, moving with a velocity of 240 i hat bold Mm/s.
A diesel cycle, with compression ratio of 18 operates on air with a low pressure of 200KPa and a low temperature 200C . If work out put is 1000Kj/Kg , determine the thermal efficiency and the MEP.
Assume that the funding can be set aside in an account that earns 5% interest per year. What is the lump sum to be set aside now in order to cover the $48,000 in annual maintenance costs?
An ideal Diesel cycle with air as the working fluid has a compression ratio of 22 and a cutoff ratio of 2.5. At the beginning of the compression process, the working fluid is at 14.7 psi, 80 °F, and 112 in3. Use the cold-air standard assumptio
