In the Venturi effect, in the reduction in pressure and increase velocity on the inside of the convergent cone, does the exit of the liquid on the divergent side mean the pressure that is increased (velocity decreased) can only increase to the maximum pressure that was achieved on the inside...
Venturi meter help!
Homework Statement
A venturi meter is measuring the flow of water; it has a main diameter of 3.0 cm tapering down to a throat diameter of 1.0 cm. If the pressure difference is measured to be 16 mmHg, what is the speed of the water entering the venturi throat...
A venturi meter with a 75 mm diameter throat is installed in a horizontal 150 mm diameter pipeline. The pressure at entry to the meter is 70 kN/m2 gauge and the pressure at the meter throat must not fall below 25 kN/m2 absolute. Calculate the maximum flow for which the meter may be used, given...
Air flows through this tube at a rate of 1200 cm^3/sec. Assume that air is an ideal fluid.
What is the height h of mercury (in cm) in the right side of the U-tube?
In case the picture doesn't show up, the tube is a Venturi tube. Wide end has diameter of 2cm, narrow diameter is 4 mm, and...
Homework Statement
A pair of vertical, open-ended glass tubes inserted into a horizontal pipe are often used together to measure flow velocity in the pipe, a configuration called a Venturi meter. Consider such an arrangement with a horizontal pipe carrying fluid of density p.The fluid rises to...
Homework Statement
Air flows through a venturimeter as shown below (rudimentary sketch of a typical venturi meter pictured). Neglecting frictional effects, obtain an expression for the volume flow rate in terms of pressures P1, Pthroat and areas A1, At at the inlet and the throat...
Homework Statement
on a venturi pump the fluid, air or water move through a narrow tube and increases speed and also decreases pressure. Now I have read before that the dynamic pressure and the static pressure are added to get the total pressure. How fast does the fluid have to flow to create...
hello every one :smile: i don't know if this is really the correct place for posting this question but here it goes!:wink: Can somebody tell me how the venturi metre and the filter pump work?
thanx in advance! :blushing:
A Venturi device has a diameter of 4mm at one end and a diameter of 2cm at the other. Air enters at 1200cm^3/m. Mercury is in the botom of the device. Assuming mercury's density to be 13700kg/m^3, and air's density to be 1.2kg/m^3, find how high the mercury rises. Assume air to be an ideal...
My question primarily relates to an object planing across a fluid surface.
First, does the Venturi effect only apply to enclosed systems such as pipes?
My true motives are to understand the physical forces acting on a surfboard as it travels down and across a wave.
I’m currently in...
these are the following data:
diameter(pipe)=0.1m
diameter(throat)=0.05m
difference in pressure=55kpa
Cd=0.98
question requires me to find the volume flow rate.
1)i know i need to find h(diff in pressure/density*gravity)
i have a doubt here where can i just leave the pressure in kpa...
water flow venturi meter problem! Heeeelp please :)
Hi,
The objects of my experiment where
1) to find out the theoretical and experimental pressures in a venturi tube,
2) To determin the coefficient of discharge for the venturi
here is the data i collectec...
