On july 23, 1983, air canada flight 143 required 22,300 kg of jet fuel to fly from montreal to edmonton. the density of jet fuel is 0.803 g/ml, or 1.77 lb/l. the plane had 7682 l of fuel on board in montreal. the ground crew there multiplied the 7682 l by the factor 1.77(without units) and concluded that they had 13,597 kg of fuel on board and needed an additional 8703 kg by the factor 1.77(again without units) and concluded they needed to add 4916 l of fuel. they added 5000l. on its flight, the plane ran out of fuel and crash-landed near winnipeg, hundreds of kilometers short of its destination. (there were few injuries and no fatalities.) what mistake did the ground crew make? how much fuel(in l) should they have added before takeoff?

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
