A face milling operation is performed to finish the top surface of a steel rectangular work piece 12.0 in long x 2.0 in wide. The milling cutter has four teeth (cemented carbide inserts) and a 3,0 in diameter. Cutting conditions are: cutting speed = 500 ft/min, feed = 0.010 in/tooth, and depth of cut = 0.150 in. Determine
(a) the time to make one pass across the surface and
(b) the maximum metal removal rate during the cut.
A stream of Refrigerant-134a at 1 MPa and 12 C is mixed with another stream at 1 MPa and 60 C. If the mass flow rate of the cold stream is twice that of the hot one, determine the specific volume of the exit stream.
The aluminum bar has an electrical coil imbedded in it, so that known amounts of heat can be transferred to it. Aluminum has a specific gravity of 2.70 and a specific internal energy given by the formulaU (kJ/kg)=0.94T(C).
