Air at p = 1 atm enters a thin-walled (D = 5-mm diameter) long tube (L = 2 m) at an inlet temperature of Tm₂ 100°C. A constant heat flux is applied to the air from the tube surface. The air mass flow rate is m = 105 x 10" the tube surface temperature at the exit is Ts,o= 160°C, determine the heat rate entering the tube, in W. Evalua properties at T = 400 K. q= W

Consider the following instance of the two-machine job shop with the makespan as objective (J2 || Cmax).

Apply the SPT(1)-LPT(2) heuristic to this two-machine job shop. 3. Compare the schedules found under (1), (2). 2.

A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period? To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed. Express your answer in § / hour rounded up to the nearest penny
