PRESSURE MEASUREMENT CLASS NOTES The measurement of pressure is one of the most important measurements in almost all industries. Applications needing measurement of pressure are: 1. Measurement of steam pressure in a boiler for safe operation of the boiler. 2. Pressure measurement is necessary in manufacturing and chemical industries. 3. Pressure measurement determines the…
PRESSURE DROP CLASS NOTES FOR MECHANICAL ENGINEERING It is difference of pressure between two points in a fluid flow. These two points can be at horizontal level or at different levels. (i)Pressure drop is the driving force for the flow of a fluid. (ii) Likewise temperature difference is the driving force for heat transfer. (iii)…
DESIGN OF THIN PRESSURE VESSELS FOR MECHANICAL ENGINEERS Thin vessels are common to process industries. Examples of thin vessels are LPG cylinder, boiler and distillation column. Stresses are uniform in a thin shell. Radial stress is neglected as compared to hoop and longitudinal stresses. Most common material of construction is flange quality steel. These…
