Can you measure air pressure in a party balloon?
The air pressure inside the balloon will be slightly higher than outside. This is because the air inside the balloon is slightly compressed by the elasticity of the membrane of the balloon itself. By way of illustration, if you inflate a balloon, don't tie it and just let it go, then to everyones' amusement at parties the balloon flies crazily around the room until it is fully deflated! This fun aspect of balloons occurs as a result of the higher pressure inside the balloon escaping from the balloon to join the air in the room that is at normal pressure. Actually measuring the pressure inside the inflated balloon would require an experiment where the volume of pressurised air in the inflated balloon could be measured by a) measuring the volume of pressurised air inside the balloon by fully immersing the inflated balloon in a measuring receptacle full of water (with normal atmospheric pressure in the room pressing down on the surface of the water) and, then b) measuring the volume that the pressurised airinside the balloon would occupy once outside the balloon at normal atmospheric air pressure by inverting the measuring receptacle full of water (whilst held in a larger shallow tank of water so as to keep the measuring receptacle full of water once inverted - in the usual physics lab manner) and then release the air from the balloon into inverted water-filled measuring receptacle where it would gather in the top of the same. The difference in the two volumes would directly correlate with the difference in air pressure inside and outside the balloon.
What are two methods scientist use to obtain emperical evidence?
The scientific method and peer review are two methods that a scientist uses to obtain empirical evidence. Experimental design and reproduction of results are two other methods.
A compound pressure gauge for the low side of the system measures pressure in what?
A compound pressure gauge measures two scales, one in positive pressure and one in negative (below atmospheric) pressure or vacuum positive pressure is measured in pounds per square inch (psi) or kilopascals or in some cases bars (1 bar = 14.35 psi) [ the average atmospheric pressure at 1000 feet above sea level] vacuum is measured in millimeters of mercury mmHg or inches of mercury inHg
What are two different units used to measure air pressure?
The SI unit is the pascal (air pressure is about 100,000 pascal). Other units include the Bar ("standard air pressure", which approx. = that 100 kPa ), and the torr, which is approximately equal to millimetres Hg but used for measuring vacua. Air pressure is about 760 torr.
What are the two methods for rejecting heat from refrigerated cases?
The two methods for rejecting heat from refrigerated cases are Air cooled condensing units and Closed circuit coolers.
What do the two numbers recorder while measuring blood pressure represent?
systolic and diastolic
100 ton equals how many bar?
Ton is a weight and bar is a pressure. There is no conversion between the two.
What is relation between PSI and bar?
PSI and Bar are units of pressure. PSI is pounds per square inch. The conversion rate between the two is one bar is equal to 14.5038 PSI. Bar is a non-SI measurement of pressure.
What is the value of 12cfm in bar?
12cfm is a unit of flow. A bar is a unit of pressure. The two are unrelated. Please restate your question.
What is an orifice meter?
A device for measuring the flow of a liquid.
They're two numbers that are recored when blood pressure is takenwhat are the two numbers?
A person who is apt in measuring blood pressure using the sphygmomanometer records two numbers. The first one is the systolic blood pressure while the second one is the diastolic blood pressure.
How many meters is equal to 5 bar?
Meters is a unit of length, bar is a unit of pressure. You can't convert between the two.
How many feet are in a hour?
Feet and hours are two different measuring methods. Feet measure distances while hours measure time.
What is the greatest pressure from coercive manipulation?
the captor uses force and intimidation in combination with two or more methods.
Water pressure can be measured in PSI is ther any other way?
Yes, there are many ways to measure pressure. * pascal (Pa) * bar * technical atmosphere (at) * atmosphere (atm) * torr (Torr) * pound-force per square inch (psi) * psia (pounds-force per square inch absolute) --- gauge pressure plus local atmospheric pressure. * psid (psi difference) --- difference between two pressures. * psig (pounds-force per square inch gauge). * psivg (psi vented gauge) --- difference between the measuring point and the local pressure. * psisg (psi sealed gauge) --- difference between a chamber of air sealed at atmospheric pressure and the pressure at the measuring point. Check out the links for MUCH more information.
Two methods of measuring air consumption are cubic feet per minute and?
Any volume and time units can be used, however the SI unit for volume flow m3/s
What is the unit for measuring the volume of sound?
There are two: the bel, or more commonly, the decibel, which is a logrithmic representation of the pressure of a sound, and the phon, which is a measure of how loud a sound is perceived.
