1. What effect does friction have on a flexible system?

The steady-state data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1200K and 400K, respectively. For each case, evalutate the net power developed by the cycle, in kW, and the thermal efficiency.

The difference between ideal voltage source and the ideal current source

Identical wire loops are dipped into liquid a and liquid b, so that a film of liquid forms across the loops (like the bubble solution on a child's bubble blowing wand).

The statement that is NOT true about the concept of a boundary layer on an object is: a. the Reynolds number is greater than unity. b. viscous effects are present only inside the boundary layer. c.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.
