A150.00 mm sine bar is used to inspect a part angle that has a dimension of 35.0? 1.0°. the sine bar rolls have a diameter- 25.0 mm. a set of gage blocks is available that can form any height from 10. mm to 199.995 mm in increments of 0.005 mm. all inspection is performed on a surface plate. determine (a) the height of the gage block stack to inspect the minimum angle, (b) the height of the gage block stack to inspect the maximum angle, and (c the smallest increment of angle that can be set up at the nominal angle size.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
