Water flows through a duct of varying area. The difference in stagnation pressures between two sections is 4.5 x 10^5 N/M^2

A). If the water remains at a constant temp, how much heat will be transferred in this length of duct?

B) If the system is perfectly insulated against heat transfer, compute the temperature change of water as it flows through the duct.

Contained in a cylinder fitted with a piston : Argon gas initially at 140 kPa, 10C is contained in a cylinder fitted with a piston. The initial volume of the gas is 0.2m^3. The gas is now compressed in a poly tropic process, PV^(1.4)=constant, to a final pressure of 700 kPa assuming ideal gas beh..
Find equation for the steady state temperature distribution : A very large vertical steel plate that is 1 cm thick is inductively heated with internal heat generation rate of 2x10^9 W/m3 . The plate is initially at 20°C, and the left and right surfaces are kept at 20°C throughout the heating process.
Temperature difference between the hot and cold streams : A vortex tube is used to separate an ideal gas at 10 bar and 375 K such that half the gas is collected in a cool stream at 1 bar and 255 K and the other half becomes a hot stream at 1 bar and 495 K. Assuming the process is adiabatic: is this process ..
