5. (10 points) air at a pressure of 2 bar, a temperature of 52oc and a mass flow rate of 0.45 kg/s enters an insulated duct having different inlet and exit diameters. the diameter of the duct exit is 5 cm, the exit velocity is 225 m/s, and the pressure at the exit is atmospheric. (5a). (4p) determine the temperature of the air at the exit. (5b). (6p) determine the rate of entropy generation within the duct.

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
