Gasoline flows in a smooth pipe with a 40 cm diameter at a rate of 0.001 m3/s. if it were possible to prevent turbulence from occuring, what would be the ratio of head losses for the actual turbulent flow compared to that if it were laminar?

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
