Aproduct whose annual demand=80,000 units is produced on a manual assembly line. the line operates 50 wks/year, 5 shifts/wk, and 7.5 hr/shift. work content time 48.0 min. line efficiency = 0.97, balancing efficiency = 0.93, and repositioning time - 8 sec. determine (a) hourly production rate, (b) number of workers, and (c) number of workstations if the manning level is 1.4.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
