One pound mass of water in a piston-cylinder assembly, initially a saturated liquid at 1 atm, undergoes a constant- pressure, internally reversible expansion tox=90%. determine the work and heat transfer, each in btu. sketch the process on p-v and t-s coordinates, associate the work and heat transfer with areas on these diagrams.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Aspherical thermocouple measurement errors a spherical thermocouple made of constantin transfer coefficient between the gas and the thermocouple is h used to measure the temperature of a gas. the heat 400 w/m2 k. calculate the maximum diameter d of the thermocouple if the thermocouple's measurement error should be w 23 within 5% of the initial temperature difference in 5 seconds. for constantin, k 8920 kg/m3, and c 410 j/kg. k.
