You are the scheduler for a large commercial building project. The schedule that you prepared (based on feedback from the project manager) falls 15 days short of the owner’s deadline. The project manager decides to write a memo to all of the subcontractors, requiring them to work 6 days per week, 10 hours per day. You ask the project manager to wait until you determine the most efficient way to crash the project. Summarize your argument in 4 short items to convince the project manager to go with a certain accelerating plan that focuses on the critical path and not all activities.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
