Answer / prateek jha

Flow Rate is usually used in industries working on
hydraulic and pneumatic areas to specify the amount of
working fluid passed across a fixed cross-section areas in
fixed time. Mostly, we describe flow rate in Litre Per
Minute means how much litres of working fluid has been
passed through a given cross-section area in One minute.
Flow Rate is independent of pressure in
hydraulic i.e liquid. but is dependent on pressure in gases
as gases are compressible at pressure. Hydraulic is also
compressible but at higher pressure.

Answer / bhaskar msc

flow rate is besed on the terms

ie, Turndown and Rangeability

turndown means ratio of full scale range to minimum scale

Rangeability means ratio of maximum rane to min range


thats the flow is based on the two terms

Why 4-20 amps is being used in instruments? Why cant we use any other range instead of 4-20 amps? Why only 4 amps is taken as lower limit and why 20 amps is taken as the higher limit?

A temperature sensor (RTD) connected via a temperature transmitter is adjusted to give an output of 4ma at 60 deg and 20 ma at 600 deg. This output (4-20ma) from the transmitter is connected to an IGBT-inverter to control a high speed (-12,000 to +12,000 RPM) DC motor. And in the inverter it is programmed as, for 4ma the motor speed will be -3,000 RPM and for 20ma the motor speed will be +10,000 RPM. The question is : If the motor speed is +5,500 (RPM), what will be the temperature? (-sign indicates that the motion is in reverse direction).
