Air changes per hour is a measure of how many times the air within a defined space (normally a room or house) is replaced.
The actual percentage of an enclosure's air which is exchanged in a period depends on the airflow efficiency of the enclosure and the methods used to ventilate it. The actual amount of air changed in a well mixed ventilation scenario will be 63.2% after 1 hour and 1 ACH. In order to achieve pressure, the amount of air leaving the space and entering the space must be the same.

How is the calculation of 24 hour urine creatinine done?
To calculate the 24-hour urine creatinine, the amount of creatinine excreted in the urine over a 24-hour period is determined by collecting all urine passed during this time. The creatinine concentration in this pooled urine sample is then measured. Finally, the creatinine concentration is multiplied by the volume of the urine collected to obtain the total amount of creatinine excreted in a 24-hour period.
How much time is required to administer 200ml of glucose iv solution?
The time required to administer 200ml of glucose IV solution would depend on the rate of administration, typically measured in ml per hour. For example, if the rate is set at 100ml per hour, then administering 200ml would take 2 hours.
What changes in the colour of iron nails and coppper sulphate solution do you observe after keeping the iron nails in copper sulphate solution for about half an hour?
After keeping iron nails in a copper sulfate solution for about half an hour, you will observe that the color of the iron nails changes to a reddish-brown due to the deposition of copper on the surface of the nails. The blue color of the copper sulfate solution will fade as copper is transferred from the solution to the nails.
What does ng 10 kt mean?
"ng 10 kt" likely refers to a wind speed of 10 knots measured at a specific location. In meteorology, a knot is a unit of speed equal to one nautical mile per hour.
When a quantity of electricity is converted to heat the heat energy is measured in what?
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
What can be measured in kilometres per hour and miles per hour?
Speed.
What speed is measured in kilometers per hour and time is measured in hours the unit of acceleration is?
Divide speed by time. In this case, you get (kilometers / hour) / hour, or kilometers/hour2. That means, how much does the speed change in an hour.

Is speed always measured by miles per hour?
No. Speed can be measured in other ways as well, such as km per hour and meters per second.
What is the units used to measure rainfall and humidity and wind?
I think rain is measured in millilitres (ml).
What is tells fast something changes position?
Speed. Speed is a measure of how quickly an object changes position over time, with units typically measured in distance per unit of time (such as kilometers per hour or meters per second).
