Two identical, sealed, and well-insulated jars contain different gases at the same temperature. each container contains the same number of moles of gas. container 1 contains helium, a monotomic gas with a molecular weight of 4.0 kg / kmol. container 2 contains co2 , a triatomic linear molecule with a molecular weight of 44 kg / kmol.

(a) which gas has higher internal energy?

(b) which gas has higher translational energy?

(c) which gas has higher pressure?

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
