Part X requires machining on a milling machine (operations A and B are required). Find the number of machines required to
produce 3000 parts per week. Assume the company will be
operating 5 days per week, 18 hours per day. The following
information is known:
Ext. If the milling machine requires tool changes and
preventive maintenance after every lot of 500 parts.
These changes require 30 min.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

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.
