#### exists and is an alternate of .

No. Pascal's Principle states that a pressure applied to a fluid system at rest is felt throughout the entire system. This means that, regardless of pipe diameter, city pressure is felt everywhere. Decreasing pipe diameter will only reduce the flow rate of the water, due to more head loss when the water moves.

If the flow is subsonic the pressure will increase, if however it is supersonic the pressure will decrease.

# Why pressure decreases when velocity increases?

Bernoulli (or Venturi) Effect examines the relationship between pressure and velocity. The equation is P + (1/2)(density)(v^2)= P + (1/2)(density)(v^2) so as pressure velocity increases, pressure will decrease and vice versa.

# Does the pressure in the atmosphere increase or decrease?

Going farther up into air, pressure decreases. Going down, pressure increases. When you think about it, more air is pressing down on you when you are standing on earth because more is on top of you. When you are up in the air, there isn't as much air pressing on you which shows that there isn't as m ( Full Answer )

# Why does voltage decrease when diameter of a wire increases?

If you are referring to the voltage drop on a wire decreasing as the diameter of a wire is increased, it is because there is less resistance in the larger wire than the small one. Doesn't take as much voltage to push through the conductor.

# What happens to boiling water if the pressure increases or decreases?

If pressure increases and temperature remains the same, then the water would stop boiling. If pressure decreases and temperature remains the same, then the water would boil more and more ferochiously. As water transforms to steam, this process takes up a lot of energy and this regulates the actua ( Full Answer )

# If you increase force does the pressure decrease?

No. Pressure is the amount of force that acts on a given area of an object. If you increase force the pressure increases as well. :)

# How can pressure be increased or decreased?

Increase pressure: decrease volume, increase temperature, increase moles of substance. Decrease pressure: do the reverse

# Why pressure increases when area decreases?

because the pressure is spread over a bigger surface area making there less pressure on a certain point

# Does ADH increase or decrease blood pressure?

Increase. ADH is an anti diuretic hormone, so it wants to maintain water inside the body. The greater presence of ADH, the more water is reabsorbed from the urine by the kidneys, and the more water enters the blood circulation. Larger blood volume means greater blood pressure.

# When pressure decreases dose volume increase or decrease?

Think of a balloon. Let some air out and the pressure goes down, and the balloon decreases in size.

# Why does air pressure decrease with an increase in altitude?

Air pressure decreases with an increase in altitude because thehigher you are, the less air there is above weighing down upon you. This is because air behaves much like water. If you are swimming,the deeper you dive, the greater you feel the pressure build,because there is more water above weighing ( Full Answer )

# How pressure drops can increase pipe life?

The more pressure = the more flow = the more wear on yourresistance like bends and fittings etc.

# When you inhale does pressure decrease inside or increase?

The act of inhaling is to create low pressure in the lungs, causing the air in the atmosphere to rush in as it is moving from a higher pressure (outside in the atmosphere) to the lower pressure (created in the lungs). However the fact that air does move into the lungs means that there is no net chan ( Full Answer )

# What happens to speed of water in a pipe if the diameter of the pipe is decreased?

Assuming that the pressure remains at a constant, reducing the diameter of the pipe will increase the water flow. On the contrary, increasing the diameter would cause the water to flow at a much slower rate.

# What is formula for pressure at known water flow and pipe diameter?

There isn't one. Pressure in a piping system will be determined by the pump, or head of water if it is a gravity feed system.

Pressure effected by the volume of substance being pushed through. For instance, the longer the hose, the more water being pushed through=greater pressure. The shorter the distance the less water being pushed through=less pressure.

# What is the rate of water flow through a 100mm diameter pipe with 300mm head pressure?

300mm is a very low head, you can't expect much flow through thatpipe, but you can work it out from the mechanical energy balanceequation.

# How does pressure and pipe diameter relate to water velocity?

The smaller the pipe and the more turns, the more resistance to the flow of water.

# Does pressure of exact amount water flowing through pipe with same length but different diameter change?

Try this : If the water stands still then the pressure is the same throughout. If the water is moving THEN it has kinetic energy ... which comes from somewhere. Thus the faster its moving, the lower the pressure. And the smaller the tube - in order to move the same amount of water (your cond ( Full Answer )

# How do you calculate water flowing out of pipe which is having a diameter of 4 inches and pressure of 4 bar?

You'll need the length of the pipe, because that's where the flow resistance is. At the outlet end, the pressure is atmospheric.

# Does decreasing pipe diameter increase pressure of gas?

Decreasing the pipe diameter for the same flow volume increases the flow rate and therefore reduces the pressure of the gas by Bernoulli's principle.

# Why the pressure of the atmosphere decreases with increasing altitude?

The earth's gravity has less pull on the atmosphere, therefore the pressure exerted on an object at a higher altitude will be less. Similarly, as you get closer to the core of the earth there will be much more atmospheric pressure exerted on you.
