A boiler with 80% efficiency produces steam at 40bar and 500 C at a rate of 1.128kg/s.
The temperature of the feed water is raised from 25 C to 125 C in the economizer and the
ambient air is drawn to the boiler at a rate of 2.70 kg/s at 16 C. The flue gases leave the
chimney at rate of 3 kg/s at 150 C with specific heat of 1.01 kJ/kg.K. The dryness fraction
of steam collected in the steam drum is 0.95.
1- Determine the heat value of the fuel.
2- The equivalence evaporation.
3- Draw the heat balance sheet.

- A rotating shaft is made of 42 mm by 4 mm thick cold-drawn round steel tubing and has a 6 mm diameter hole drilled transversely through it. The shaft is subjected to a pulsating torque fluctuating from 20 to 160 Nm and a completely reversed bending moment of 200 Nm. The steel tubing has a minimum strength of Sut = 410 MPa (60 ksi). The static stress-concentration factor for the hole is 2.4 for bending and 1.9 for torsion. The maximum operating temperature is 400˚C and a reliability of 99.9% is to be assumed. Find the factor of safety for infinite life using the modified Goodman failure criterion.arrow_forwardI need help with a MATLAB code. This code just keeps running and does not give me any plots.
