## What is the volume of a gas at STP?

22.4 L

## What is the volume of the sample at STP?

At STP one mole of any gas occupies a volume of 22.4 L: this is the molar volume. Notice: the second value of the variable is the first value multiplied by fractions of the other two variables. EXAMPLE: A gas sample occupies a volume of 125 mL at STP.

## How hot will a 2.3 L balloon have to get to expand to a volume of 400 l?

1 Answer. The temperature needs to be 390 K.

## What is the new volume if 60.0 mL of gas is cooled from 33.0 C to 5.00 C?

Problem #4: What change in volume results if 60.0 mL of gas is cooled from 33.0 °C to 5.00 °C? The volume decreases by 5.5 mL.

## What happens to the volume when the pressure doubles?

For a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure. That means that, for example, if you double the pressure, you will halve the volume. If you increase the pressure 10 times, the volume will decrease 10 times.

## Does water volume affect pressure?

The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. The most remarkable thing about this expression is what it does not include. The fluid pressure at a given depth does not depend upon the total mass or total volume of the liquid.

## What is difference between pressure and volume?

Pressure vs Volume – Whats the Difference? To explain a piping system, the word “pressure” is used to describe the measure of force which plays a vital role in the operation of water equipment like tanks, vessels, pumps and other devices. Volume determines the quantity of water held in a pipe, tank or other device.

## What is the difference between water pressure and water volume?

Water pressure is the amount of force that pushes water through the pipes and it’s normally determined by the water company. Water volume is the actual amount of water that flows through the faucets and taps. The volume is regulated by the pipes in the house and the aerators at the end of the taps.

## Does flow rate change with pipe diameter?

Flow rate varies inversely to length, so if you double the length of the pipe while keeping the diameter constant, you’ll get roughly half as much water through it per unit of time at constant pressure and temperature.

## What size should main water line be?

In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.

## How do I calculate water line size?

There are three steps to calculating the proper size for a plumbing piping system:

- Add up the total number of water supply fixture units (wsfu) required in the facility.
- Estimate demand using the table from the IPC that correlates wsfu to expected demand.
- Size the pipe using demand vs.

## What is the best pipe for main water line?

Galvanized Piping Galvanized metal is commonly used in construction, but pipes made from galvanized steel can be used in plumbing applications. This particular type of pipe is best used for water lines, as gas lines can cause the zinc to corrode and damage the pipe or block the entire system.

## How do you measure the diameter of a pipe?

Here are a few ways to measure:

- Direct Diameter measurement is the easiest. Measure at the end of the pipe.
- Direct Diameter measurement with a caliper (useful if the end is not accessible) 1 1/2″ pipe.
- Measure circumference using a flexible tape and divide the outside circumference by 3.1415.

## Are pipes measured by inside diameter?

When it comes to measurement of pipe, it is measure by the inside diameter, often called the nominal diameter. Nominal Pipe Size (NPS) is a North American set of standard sizes for pipe.

## How do you measure a diameter?

Measure just the radius of the circle if it is very large. The radius is the distance from the center to any point on the circle. Multiply the radius by two to produce a measurement for the diameter.

## What is the diameter of a 9 inch circle?

Area and circumferences of circles with diameters in inches

Diameter (in) | Circumference (in) | Area (in2) |
---|---|---|

9 1/8 | 28.67 | 65.40 |

9 1/4 | 29.06 | 67.20 |

9 3/8 | 29.45 | 69.03 |

9 1/2 | 29.85 | 70.88 |

## How do you find the inner diameter from the outside diameter?

Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle.

- Find the Diameter.
- Look at Thickness.
- Double the Thickness.
- Subtract to Find Internal Diameter.

## How do you find the internal diameter?

Inner diameter can be measured by inserting a plug type measuring head with air blow noz- zles on both sides. Taper can be measured by moving the head in the axial direction. The average inner diameter can be measured by placing three or more jets at equiangular locations.

## What is the diameter of 3 inches?

2 1/2 | 7.854 | 4.909 |

2 3/4 | 8.639 | 5.940 |

3 | 9.425 | 7.069 |

3 1/4 | 10.210 | 8.296 |
