62 m3/s of air enters a combustion chamber of a jet engine at a velocity of 148 m/s at -25 °C and 36 kPa. The air leaves the chamber at 1,127 m/s at 367 °C. Determine the fuel (in kg) consumed during a 30 minute flight. Assume that changes in air mass flow rate through the chamber are not significant and LaTeX: \Delta h\cong C_P\Delta T. Take the air gas constant to be 0.287 kPa. m3/kg. K , the specific heat of air to be 1 kJ/(kgK) and the heating value of the fuel to be 44,823 kJ/kg. Give your answer to the nearest kg.

Ashielded metal arc-welding operation is accomplished in a work cell by a fitter and a welder. the fitter takes 5.5 min to load components into the welding fixture at the beginning of the work cycle, and 1.5 min to unload the completed weldment at the end of the cycle. the total ength of the weld seams 1200 mm, and the travel speed used by the welder averages 300 mm/min. every 600 mm of seam length, the welding stick must be changed, which takes 0.8 min. while the fitter is working, the welder is idle (resting): and while the welder is working the fitter is idle. (a) determine the average arc-on time as a fraction of the work cycle time. (b) how much improvement in arc-on time would result if the welder used flux-cored arc welding (manually operated), given that the spool of weld wire must be changed every 10 weldments, and it takes the welder 5.0 min to accomplish the change? (c) what are the production rates for these two cases (weldments completed per hour)? attach your work and solutions.
