For a turning operation, you have selected a high-speed steel (hss) tool and turning a hot rolled free machining steel. your depth of cut will be 0.105 in. the diameter of the workpiece is 1.00 in. a. using a speed of 105 sfpm and a feed of 0.015, calculate the metal removal rate (mrr).

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
