Acontainer holding 1.5 moles [mol] of oxygen (formula: upper o2, molecular weight equals=32 grams per mole [g/mol]) at a pressure of 2.5 atmospheres [atm] and a temperature of 310 kelvins [k] is heated to 410 kelvins [k], while maintaining constant amount and volume. what is the new pressure inside the container in units of pascals [pa]?

On a average work day more than work place firs are reorted

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk

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
