Thermal Center - Metallurgical Fundamentals of Heat Treating

Fundamentals of Heat Treating:Ideal Diameter. A quantitative measure of a steels hardenability is eed by its DI, or ideal diameter, value. This abbreviation comes from the French phrase diamètre idéal and refers to the largest diameter of steel bar that can be quenched to produce 50% martensite in its center (Fig. 4). WIRE EDM THE FUNDAMENTALSWIRE EDM THE FUNDAMENTALS BY DONALD B.

What is Head Loss - Pressure Loss - Definition

Water at 20°C is pumped through a smooth 12-cm-diameter pipe 10 km long, at a flow rate of 75 m 3 /h. The inlet is fed by a pump at an absolute pressure of 2.4 MPa. The exit is at standard atmospheric pressure (101 kPa) and is 200 m higher. Calculate the frictional head loss H f, and compare it to the velocity head of the flow v 2 /(2g).
