How can the hot water be at a higher pressure than the cold mains in an unvented system?
Pressure temperature relationship will tell you all you need to know
How do you Convert 20 liters gas to kilograms?
you need to know the density of the gas (and temperature and pressure)
Why does the air in a balloon condense in refrigerator?
This is fully explained by the Ideal Gas Laws. Temperature, volume, and pressure are all directly inter-related in a gas. Lower temperature creates less pressure which creates a smaller balloon. If you really want to know why this happens, you need to understand what temperature is and what a gas is. Temperature is actually the average kinetic energy of the constituent particles, and a gas is a collection of independently moving atoms or molecules, so, imagine all these molecules of air, whose speed is measured by their temperature. The faster they move, the more force they exert when they collide with the balloon. The more force they exert, the more inflated the balloon will be. It makes perfect sense.
How do you calculate the subcooling in HVAC?
To calculate subcooling in HVAC, you need to measure the liquid line temperature and pressure. First, convert the pressure into temperature using a temperature-pressure chart. Subtract the liquid line temperature from the converted temperature to calculate the subcooling. Subcooling is important to ensure the liquid refrigerant leaving the condenser is cooler than its saturation point to prevent the formation of flash gas in the metering device.
Why would you want to put a fluid under pressure?
When a fluid is put under pressure, the volume decreases and the temperature may rise a tiny bit because the particles are compressed.
What is sublimation point?
Salt ... ordinary table salt ... melts rather than sublimes at normal pressures. To find the sublimation point, you'd need to specify a pressure and look at a phase diagram. The sublimation point would be the point on the solid/gas phase boundary where the pressure is equal to your specified pressure. I'm sorry I can't be more exact, but that's just the way it is; normally when people talk of "melting points", "boiling points", or "sublimation points" it's assumed that they're talking about a system at "standard pressure" (about 100 kPa), and sodium chloride does not sublime at that pressure at any temperature.
At what temperature does dry ice sublimate?
At Earth's standard pressure (1 atmosphere or atm), dry ice sublimes at −78.5 °C , which is −109.3 °F.
What factors affect sublimation?
If there is high pressure, the sample is physically prevented from easily making the phase change at a constant temperature. PV= nRT solid --> liquid --> gas S-->L at high pressure decreases the mp L -->G at high pressure increases the bp and the temp at vaporization Analogous to glaciers melting, ice under high pressure will melt. Analogous to boiling an egg in Boston (sea level) or in Denver (1 mile above sea level). Which takes longer? Boston, b/c the the pressure at sea level is greater, so the bp is higher. In Denver, there is less vapor pressure (ie, the air above the pot with the egg), so the temp of boiling is lower.
What does a compound pressure gauge measure?
i need to explain what an absolute pressure gauge measures
What is the proccess of a gas to a solid?
The process is sublimation:] if you need this for a project google gas to solid sublimation
I need to know how many milliters for eight millgrams.?
you need to know the density, temperature and pressure for water at standard temperature and pressure then 8mg = 8ml for other liquids/temperatures it will be different
What is happening to energy in sublimation?
Sublimation is an endothermic phase transition.Sublimation is the transformation of a solid in a gas, directly, and need energy for this.
Why need high temperature in diffusion process?
probably because the particles move faster when they have more energy. If the particles are moving faster then they will mix (diffuse) faster.
How does the body benefit from a change in blood pressure during exercise?
As one exercises, they need more blood, faster. They need more faster because energy and oxygen are being used at a faster pace. The increase in blood pressure during exercise allows for the blood to flow at its maximum efficiency.
What is the maximum pressure schedule 40 galvanized pipe can take?
Need to know the pipe diameter. 3 inch is the diameter of the galvanized pipe what is the working pressure of the pipe
What factors can affect the solubility?
Temperature, Pressure, Polarity, Surface Area, and Agitating the Mixture.
What does matter need in order to change from one state to another?
A change of the temperature or pressure.
