Suppose the part in previous Problem 2.5 is made in very large quantities on a production line in which an automated work handling system is used to transfer parts between matches. Transfer time between stations = 15s.The total time requited to set up the entire line is 150hr. Assume that the operation times at the individual machines remain the same. Determine:
(a) manufacturing lead time for a pari coming off the line,
(b) production rate for operation 3,
(c) theoretical production rate for the entire production line?
Problem 2.5
A certain part is routed through six machines in a batch production plant. The setup and operation time' for each machine are given in the table below. The batch size is 100 and the average non operation time per machine is 12 hr. Determine:
(a) Manufacturing lead time and
(b) Production rate for operation 3.
A practical integrator. Note that the resistor in parallel with the feedback capacitor provides a path for the capacitor to discharge the DC voltage. Usually, the time constant RF CF is chosen to be long enough not to interfere with the integration..
Atmospheric pressure is101.3 kPa (or else 14.69 psi). You take a vessel, and pressurise it to 350 kPa (or 50.75 psi) above the atmospheric pressure, and connect pressure gauges to the vessel, calculate What is the gauge pressure? What is the absolute..
A Mode1.1 Wagon is to be assembled on a conveyor belt. 500 wagons are required per day. Production time per day is 435 minutes. The assembly steps and times for the wagon are given in the Table. Uptime for the line is expected to be 98% and reposi..
How does artificial aging affect KIC in a 7075 alloy? Which is likely to have a higher KIC: 7075-T6 or 7075-T7? Explain.
Liquid octane (C8H18) at 778F, 1 atm enters a combustion chamber operating at steady state and burns completely with 50% excess dry air entering at 1208F, 1 atm. The products exit at 10608F, 1 atm. Determine the rate of heat transfer between the c..

Calculate the final temperature of the helium in the cylinder assuming that the heat transfer during the process is negligibly small. Take for helium as 112 kl/kg K.
In what types of situations is it advantageous to have a single crystal material instead of a multi-grained material? What are the challenges in creating a single crystal? How do they create them?
Consider a 1.25 cm diameter carbon steel (1% C, k = 40 W/m-K) sphere to be cooled from 500oC to 100oC by a cooling air flow at 25oC with convection coefficient of 110 W/m2-K.
