Alternatively, the general contractor could do the work using their own excavator. They have a CAT 349F L with a Long Reach Boom, (Belgium Sourced) with a 80 in. wide General Duty High Capacity bucket. The contractor has no trench box and the side slopes of the trench will have to be at a 1:1 slope to the bottom of the trench in order to be safe. The bottom of the trench will be 6.6 feet wide (due to size of bucket). Without the trench box, the contractor estimates it will take 10 minutes to lay a joint of pipe. Could the job be completed more quickly with the CAT 349F L

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
