Compute the concentration of carbon at 0.2 mm from the carbon-free surface of the 1030 steel bar after 1 hour in vacuum at 1000 degrees Celsius. Take the initial carbon concentration of the 1030 steel bar to be 0.3 wt%.
A piece of steel has a conductivity of k= 15 W/mK, and a brick has k=1W/mK. How thick a steel wall will provide the same insulation as a 10cm-thick brick?
Low-velocity steam (with negligible kinetic energy) enters an adiabatic nozzle at 300 C and 3 MPa. the steam leaves the nozzle at 2 MPa with a velocity of 400 m/s. the mass flow rate is 0.4 kg/s.
A Brayton cycle operates with inlet air at 14 psi and 80F. The turbine inlet temperature is 1800 F and the pressure ratio is five.
While trapped in a cylinder, 2.27 kg of air is compressed isothermally (with a water jacket being used around the cylinder to maintain constant temperature) from initial conditions of 101 kPa and 16 celsius degree to a final pressure of 793 kPa.
