An ideal gas undergoes two processes: one frictionless and the other not. In both cases, the gas is initially at 200 oF and 1.5 atm, and when the process is over, the gas is at 700 oF and 22 atm. For which process does the gas experience a greater change in entropy

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
