2. A parallel-plate capacitor initially has a capacitance of 100 F. What will be the
capacitance if the distance between the plates is doubled?
A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid.
At the inlet to a certain nozzle, the specific enthalpy of the fluid is 3320 kJ/kg and
the velocity is 60 m/s. At the exit from the nozzle the specific enthalpy is 2530 kJ/kg.
The nozzle is horizontal, and the heat supply, the heat loss, the work input, and the
work output to or from the nozzle are all negligible.
(a) Determine the velocity at the nozzle exit
