C++ Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90.

Your program will prompt the user to type a highway number ("Please enter a highway number, Ex: 65: "), read in the number typed by the user, and print out whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves.

Also your program must indicate if the (primary) highway runs north/south or east/west, that it is an invalid number if not between 0 and 999.

Superheated vapor enters the turbine at 10 MPa, 480°C, and the condenser pressure is 7.5 kPa of a steam Rankine power cycle. Isentropic efficiencies of the turbine and pump are 84% and 73%, respectively. Determine for the cycle

a. Sketch the cycle of a T-s diagram. Indicate the isobars with their values and the values for temperature and entropy.

b. The heat transfer to the working fluid passing through the steam generator, in kJ per kg of steam flowing.

c. The thermal efficiency.

d. Compute the entropy generated by the turbine per unit of mas of steam flowing.

e. The heat transfer from the working fluid passing through the condenser to the cooling water, in kJ per kg of steam flowing. [Hint: this refers to the cooling tower]

A pump steadily delivers 8.94 kg/s of water at the conditions given below. Calculate the pump power (hp).

The rate of heat transfer from the pump to the surroundings is Q = 1.61 kW.

There are no changes in kinetic or potential energy.

Pump Inlet Temperature = 50oC

Pump Inlet Pressure = 1.75 MPa

Pump Exit Temperature = 50oC

Pump Exit Pressure = 4.17 MPa

The circular fin of diameter D=1mm and length L=25.4mm, made of copper (k=400 W/m.K), are used to enhance heat transfer from a surface that is maintained at temperature Tb=132 °C. and the rod has another end attached to a large surface which is maintained at Te= 0°C. The airflow through the rod surfaces is at T∞ = 0 °C with convection heat transfer coefficient h = 100 W/m2.K. (Hint: use table 3.4 in the lecture slides.)

(a) Express temperature T(x) along the fin and calculate the temperature at x=L/2. (5points)

(b) Determine the rate of heat transfer at the hot end of the fin (3 points) and calculate the fin effectiveness (2 points).
