Why liquid rushes faster at the bottom hole than the tops?
liquid rushes faster at the bottom hole than tops because pressure in liquids is directly proportional to the height of the liquid.that is the deeper the liquid the higher the pressure
Why do you have to put two holes in a juice can make it flow easy?
If you only put one hole, the liquid can flow out, but air cannot flow in to replace it, so the liquid soon stops running because it's filled up the hole totally. You have to replace the lost space with air to keep it running, so you need a second hole.
Why two holes are made to empty an oil tin?
The tin will be turned sideways to pour the oil. One of the holes will be above the level of the oil inside the tin. This hole will allow air to flow into the tin to replace the out-flowing oil - this will maintainthe balance of the air-pressure in the tin. If there was only one hole then the oil flowing out, and the air flowing in would have to share the hole and this would lead to the pressure in the tin varying as it would reduce when oil flowed out until that oil's volume had been replaced by air. This is what leads to the inconsistent pouring of a liquid when a bottle is tilted so much that the liquid covers the opening. The flow stops and starts.
What is the use of funnel support?
A funnel support is used to place a funnel accurately into a container or beaker or maybe even a flask in order to concentrate the flow of liquid into the container which happens through the funnel
How the current flow through npn?
A; The base must be positive with respect to the emitter this condition will allow collector current to flow from collector to emitter. If the transistor manage to get saturated the current can flow in both direction. as a switch
Why are two opposite holes needed to let liquid out of a can?
It's not needed actually, it just helps the overall flow. One hole is for getting the liquid out, the other lets air inside the can to help it flow faster.
Why liquid rushes faster at the bottom hole than the tops?
liquid rushes faster at the bottom hole than tops because pressure in liquids is directly proportional to the height of the liquid.that is the deeper the liquid the higher the pressure
How can you allow honey to flow out of a can without opening it?
Poke a hole with your fingernails.
Which melts faster ice with hole in middle or cubed ice?
Cube ice with a hole in the middle will melt faster. The hole increases the surface area and will allow more of the ice to melt at the same time.
How does 94 drain plug work?
A drain plug is just a bolt used to plug a hole preventing liquid flow from that hole.
Why do you have to put two holes in a juice can make it flow easy?
If you only put one hole, the liquid can flow out, but air cannot flow in to replace it, so the liquid soon stops running because it's filled up the hole totally. You have to replace the lost space with air to keep it running, so you need a second hole.
Why does a liquid flow at longer distance when a hole is made at the centre of the container?
because liquid exerts more pressure more at the bottom tan at the top
What are the relationship between viscosity and time of flow?
When a liquid is heated, it will generally become less viscous.
What does an orifice look like?
Generally a very small hole to allow a limited amount of gas or liquid to pass.
Why does piercing two small holes in the can will allow the milk to flow out faster?
As the milk comes out, it has to be replaced with something. (usually air) Otherwise a vacuum will form and stop the milk from leaving the can. Piercing another hole opposite to where the milk comes out, allows air to rush in, stops a vacuum forming and allowing the milk to flow freely.

Why is it difficult to pour juice from a can if only one hole is punched in it?
It is because liquid flow requires a certain level of oxygen(air) to move out of the can.
