A new coal-fired power plant has been built using a sulfur emission control system that is 70 percent efficient. If all of the sulfur oxidizes to SO2 and if the emissions of SO2 are limited to 0.6 lb SO2 per million Btu of heat into the power plant, what maximum percent sulfur content can the fuel have? (a) If 15,000 Btu/lb coal is burned?
(b) If 9,000 Btu/lb coal is burned?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
