1Flow rate measurement devices require accurate pressure and temperature measurements
- ATrue
- BFalse
2What happens at a thin plate orifice
- AHigh pressure drop
- Blow pressure drop
- Cminimum flow occurs at vena contractor
- Dmaximum flow occurs at ven contractor
3What occurs at a long radius nozzle
- Ahigh pressure drop
- Blow fluid energy losses
- Clow pressure drop
- Dhigh fluid energy losses
4Venturi tube have
- Alow accuracy
- Bhigh accuracy
- Chigh pressure drop
- Dlow pressure drop
- Elow cost
5Pitot-static tubes are placed in flow with axis parallel to flow
- ATrue
- BFalse
6Pitot-static tubes have two pressure sensing locations on the port
- ATrue
- BFalse
7Pitot-static tubes measure fluid velocity in liquid and gas
- ATrue
- BFalse
8A Pitot-probe is different to a pitot-static because
- Astatic pressure is measured
- Bstatic pressure is not measure
- Cthey are bigger
- Dthey are smaller
- Ethey have a better spatial resolution
9Laser Doppler effect is a non intrusive but very precise, quantitative measurement of fluid velocity
- ATrue
- BFalse
10reflected light from object is scattered, the frequency is not proportional to the speed of the object
- ATrue
- BFalse
11The difference between incident and scattered light frequencies is the Doppler shift?
- ATrue
- BFalse
12Dual beam LDA, lens focusses two beams at a point at which they cross in the flow, velocity is determined at focal point, interference does not produce a fringe pattern
- ATrue
- BFalse
13Differential pressure devices- if density is known a measurement of differential pressure determines the liquid depth
- ATrue
- BFalse
14Capacitance devices- capacitance can be converted to voltage that is a function of fluid level, capacitance depends on dielectric coefficient of fluid in tank
- ATrue
- BFalse
