Answer / ankurjha

In simple words,it is like simulating a real life/on site
situation on a computer screen, wherein the input variables
can be manipulated & outcomes can be observed without
visiting the site.

Answer / kaja farkhan

virtual instrumentation is an field in which it deals with
the maniplation of inputted variables through simulation
and then we can implement these simulated ones in real.

Answer / binay

Virtual instrumentation is a revolutionary concept that has
changed the way engineers and scientists approach
measurement and automation. VI means measurement without
physical devices. VI is brought through easy-to-integrate
software, such as the NI LabVIEW graphical development
environment, and modular hardware, such as PCI modules. It
is widely used for data acquisition and instrument control.
VIs are viewable but not touchable i.e. no physical
existence but performance is like a real instrument. It
makes the computer and hardware to work for our wish.

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
