Consider the design of a nozzle in which nitrogen gas flowing in a pipe at 500 kPa, 200?C, and at a velocity of 10 m/s, is to be expanded to produce a velocity of 300 m/s. Determine the exit pressure and cross-sectional area of the nozzle if the mass flow rate is 0.15 kg/s, and the expansion is reversible and adiabatic.

Major overhaul expenses of $5,000 each are anticipated for a large piece of earthmoving equipment. The expenses will occur at EOY four and will continue every three years thereafter up to and including year 13. The interest rate is 12% per year.
Starting from the basic principles, derive a differential equation that governs the variation of the temperature of the wire as at Function of the distance x from the extrusion nozzle. Also specify the boundary conditions.
A helium balloon lifts a basket and cargo of total weight 2000 N under standard conditions, in which the density of air is 1.29 kg/m3 and the density of helium is 0.178 kg/m3. What is the minimum volume of the balloon?
1 kg of air is polytropically compressed reversibly from 5 bar to 10 bar from an initial temperature of 300oC. Find the transferred heat and the change in entropy. Take the polytropic index as 1.25.
