Cutting temperature: Orthogonal cutting is performed on a metal whose mass specific heat = 1.2 J/g‑C, density = 2.96 g/cm3, and thermal diffusivity = 0.86 cm2/s. The cutting speed is 5.6 m/s, uncut chip thickness is 0.28 mm, and width of cut is 3.3 mm. The cutting force is measured at 1190 N. Using Cook's equation, determine the cutting temperature if the ambient temperature = 25 ° C.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
