The pressure of a gas increased from 4 bar to 5 bar. Its temperature increased from 25 C to 55 C. Approximately how much was the gas compressed or expanded?
Approximately how much pressure can a 150 lb. flange withstand?
A. 60 PSIG
B. 150 PSIG
C. 180 PSIG
D. 270 PSIG
Good measurement requires both repeatability and accuracy — but good accuracy generally means good repeatability.
An orifice plate is designed to generate a differential pressure of 1,000 mm of water column at a full scale flow rate of 100 liters per minute.
What is the additional measurement range in which a flowmeter can accurately measure flow if its turndown is improved from 50-to-1 to 100-to-1?
Using the Affinity Laws, what is the approximate flow and pressure generated when a variable speed drive operates the pump motor at 70 percent speed?
My initial gut reaction is that whoever designed the piping had little or no instrumentation background. Further, all of the instrumentation work performed in conjunction with the installation is suspect.
My initial gut reaction is that this piping installation was laid out by a piping designer with minimal or no input from an instrumentation engineer or instrument designer.
Which of the following flowmeters infer the flow of fluid passing through the flowmeter? A. Coriolis mass; B. Magnetic; C. Orifice plate; D. Oscillating piston; E. Oval gear; F. Thermal; G. Turbine; H. Venturi; I. Vortex shedder …
