In a production facility, 1.6-in-thick 2-ft 2-ft square brass plates (rho = 532.5 lbm/ft3 and cp = 0.091 Btu/lbmF) that are initially at a uniform temperature of 75F are heated by passing them through an oven at 1500F at a rate of 340 per minute. If the plates remain in the oven until their average temperature rises to 900F, determine the rate of heat transfer to the plates in the furnace.

How many trips would one rubber-tired Herrywampus have to make to backfill a space with a geometrical volume of 5400 cubic yard? The maximum capacity of the machine is 30 cubic yard (heaped), or 40 tons. The material is to be compacted with a shrinkage of 25% (relative to bank measure) and has a swell factor of 20% (relative to bank measure). The material weighs 3,000 lb/cu yd (bank). Assume that the machine carries its maximum load on each trip. Check by both weight and volume limitations

Calculate the RWL and the LI for the following task.As forgings exit a cooling bath,they are loaded into various tumblers for finishing.Each forging weighs 15 pounds and is lifted from a conveyor that is 36 inches high to a tumbler that is 48 inches high.The forgings are relatively small, so the hands are only 5 inches from the waist.The process completes a forging every 10 seconds.The coupling is considered fair, and the operator works a full 8-hour shift.

You are considering purchasing a compact washing machine, and you have the following information: The Energy Guide claims an estimated yearly electricity use of 350 kW-hrs, based on 8 loads of laundry being washed per week. The Energy Guide claims an estimated yearly operating cost of $38. This estimate is based on $0.1065 per kW-hr, and eight loads of laundry being washed per week. Local electricity costs $0.086 per kW-hr. You wash four loads of laundry per week. Based on this information, first calculate the energy that would be used by this compact washing machine in a year. Then calculate the yearly energy cost. a. $3.27 b. $19.00 c. $15.34 d. $178.40

Refrigerant 134a enters a horizontal pipe operating at steady state at 40C, 300 kPa, and a velocity of 25 m/s. At the exit, the temperature is 90C and the pressure is 240 kPa. The pipe diameter is 0.1 m. Determine: (a) the mass flow rate of the refrigerant, in kg/s, (b) the velocity at the exit, in m/s, and (c) the rate of heat transfer between the pipe and its surroundings, in kW.

A man can swim at 4 ft/s in still water. He wishes to cross tje 40-ft wide river to point B, 30 ft downstream. If the river flows with a velocity of 2 ft/s, determine the speed of the man and the time needed to make the crossing. Note While in the water he must not direct himself toward point B to reach the point.

Prob. 4.2.1. A well that pumps at a constant rate of 0.5 m3/s fully penetrates a confined aquifer of 34-m thickness. After a long period of pumping, steady-state drawdowns are measured at two observation wells 50 and 100 m from the pumping well as 0.9 m and 0.4 m, respectively. Determine: (a) the hydraulic conductivity and transmissivity of the aquifer; (b) the radius of influence of the pumping well; (c) the expected drawdown in the pumping well if the radius of the well is 0.4 m.

A platinum resistance temperature sensor has a resistance of 120 at 0 and forms one arm of a Wheatstone bridge. At this temperature the bridge is balanced with each of the other arms being 120 . The temperature coefficient of resistance of the platinum is 0.0039/K. What will be the output voltage from the bridge for a change in temperature of 20? The loading across the output is effectively open circuit and the supply voltage to the bridge is from a source of 6.0 V with negligible internal resistance.
