64g of o2 is present at 25°c and 1atm pressure. molar heat capacity of oxygen at constant pressure is equal to 29.33 j/k mol. find values of q in the following processes (a) doubling the gas volume under reversible isothermal conditions (b) doubling the gas volume in isobaric conditions (c) doubling gas pressure in isochoric conditions

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

Find the minimum film thickness for a journal bearing with the data below. shaft diameter, d-50 mm, clearance ratio, cdratio? 0.001, shaft speed, n 2000 rpm; bearing length. i 200 mm; eccentricity ration, ? -0.55. ( note, cdratio-ca/d) the minimum film thickness is um

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
