Triton Manufacturing Company began June 2016 with 10,000 units of inventory in process, 20 percent completed. During the period, 50,000 units were completed and transferred to the finished goods warehouse. Ending inventory consisted of 5,000 units, 70 percent completed. Materials were added at the beginning of the process. Required: Calculate the equivalent units for: I. Materials costs under the weighted average process cost method. II. Conversion costs under the weighted average process cost method. III. Materials costs under the FIFO process cost method. IV. Conversion costs under the FIFO process cost method.

“Main landing gear of each aircraft is used to absorb the load of the aircraft in landing/ take-off and also weight of it while it is on ground. After reaching its flight cycle, it needs to overhaul to keep aircraft safe. Write an essay how to inspect, clean and lubricate the bearing of main landing gear during maintenance. Make sure the procedure is complete.”

Steam is supplied to a turbine at 50Bar, 400oC. It expands in the first stage until it is dry saturated and then reheated to 400oC before expanding in the second stage to a condenser pressure of 0.05 Bar. Calculate the work output, Specific Steam Consumption (SSC) and the Rankine efficiency Compare these values with those obtained by a single stage expansion without reheat. Note - Neglect feed pump work

A plain carbon steel ball 2 mm in diameter is heated to 1200 K in an oven and then cooled slowly in ambient air at 300 K. The convection heat transfer coefficient between air and this steel ball is 20 W / (m² * K). You can find the density, specific heat and thermal conductivity from the property tables attached in text book with reasonable assumptions. Please derive an equation estimating the changes of the temperature of this ball with time, and the time needed for this steel ball to be cooled to 400 K with the radiation heat loss ignored. Please comments if the ignorance of radiation heat loss in this question in reasonable by checking the possible contribution of radiation to heat loss at three temperature points.
