Ans1)Thorpe tube flowmeter not used with an adjustable regulator as:
- These arent used today because high resistance equipment. oxygen tube is small and its connected to flow meter it creats resistance and causes back pressure and pushes float down.
1. Why is a Thorpe tube flowmeter not used with an adjustable regulator?
Hello,
could you help me with it .
55. A flowmeter has a completely closed needle valve, and the ball jumps then retums to zero when the flowmeter is plugged into a gas source. Which of the following is correct? I aBourdon gauge is being used II it is a Thorpe tube flowmeter III. it is a back-pressure compensated flowmeter IV. the needle valve is malfunctioning A B. C. D. I & IV II & III I,II & III II,...
The Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (ρ = 7.00 ✕ 102 kg/m3)through a hose having an outlet radius of 1.28 cm. The difference in pressure is measured to be P1 − P2 = 1.70 kPa and the radius of the inlet tube to the meter is 2.56 cm. (a) Find the speed of the gasoline...

The Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (p 7.00 x 102 kg/m3) through a hose having an outlet radius of 1.47 cm. The difference in pressure is measured to be P1 P2 1.10 kPa and the radius of the inlet tube to the meter is 2.94 cm (a) Find the speed of the gasoline as it...
The venturi flowmeter shown in the figure is used to measure the flow rate of water in a solar collector system. The flowmeter is inserted in a pipe with diameter 1.9 cm ; at the venturi of the flowmeter the diameter is reduced to 0.64 cm . The manometer tube contains oil with density 0.82 times that of water. If the difference in oil levels on the two sides of the manometer tube is 1.7 cm , what is the...
A Venturi flowmeter is used to measure the flow rate of water (see the figure below). The flowmeter is inserted in a water pipe that has a diameter of 2 cm. At the narrow section, the diameter of the pipe is 0.8 cm. The U-tube contains oil with density 0.85 g/cm3. If the difference in the oil level on the two sides of the flowmeter is 1.5 cm, what is the volume flow rate of water through the pipe? The...
why can’t a precision balance be used to calibrate the adjustable pipettes. What will happen if you weigh 2.5 ul of water with the precision balance ?
A slide whistle is an open-closed tube with an adjustable plunger that changes the length. You are playing the slide whistle and pushing the plunger in at 8 cm/s when the tube is 15 cm long. What is the rate of change of the sound in Hz/s? Derivative and chain rule needed.
The Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (? =7.00 102 kg/m3) through a hose having an outlet radius of 2.86 cm. The difference in pressure is measured to be P1 - P2 = 1.40 kPa and the radius of the inlet tube tothe meter is 1.43 cm.a) Find the speed of the gasoline as it leaves...
Suppose we have a tube with adjustable length and open at both ends. The wavelength of the fundamental mode of vibration is lambda for a given length. Suppose now that the tube is adjusted to twice the given length. What happens to the wavelength of the fundamental mode? A. It is halved. B. It is doubles. C. It quadruples. D. Can’t tell without knowing the velocity of sound in air E. Can’t tell without knowing the frequency of vibration F....
