What are the units used for pressure?

I think that's dalton's law.  Whoever came up with it, the pressure is additive.  So convert so everything is in the same units, multiply by the percent, add, and then compare to the answers.  I bet it's more fun than you predict.  Whooo!  Conversion factors!  I don't want to take that kind of enjoyment away, so get cracking!

Bernoulli's equation can be used to estimate the pressure difference on the upper surface versus the lower surface, using the velocities you are given. Then recall that pressure is force per unit area, so take the pressure difference times the total area of the wings (remember you have two wings), and you have force!

G'day CathDunn04,\n\nThank you for your question.\n\nThe SI unit of measurement for force is the newton. There was an earlier unit called a dyne. The imperial equivalent was a slug.  The SI Unit was named after Sir Isaac Newton and his development of the second law of motion.\n\nI have attached sources for your reference.\n\nRegards

You are trying to convert between two dissimilar units.  Pounds per square inch (psi) is a unit of pressure, which, in more fundamental units, is force per unit area.  The "centrifugal force" (or centrifugal acceleration) produced that is a result of rotation is just that -- a force (or an acceleration).  The *pressure* exerted by a body experiencing that force depends on the contact area between that body and another object.\n\nCentrifugal force is not a true force;  it is an apparent force that results from the use of a rotating reference frame.  Although it is not a true force, it is handy for analyzing many sorts of situations.\n\n----------\n\nIf it helps, the centrifugal acceleration experienced by an object located a distance "R" from the axis of rotation in a reference frame that is rotating with an angular velocity of "w" radians/sec is given by:\n\na = R*w^2\n\nNote that 1 rpm = 1 revolution/min = 2*pi/60 radians/sec\n\nNote also that "gravities" are a unit of acceleration.  One "g" = 9.81 m/s^2\n\nThe centrifugal "force" is the mass times this acceleration.

mg are units of weight.. Spoons measure volume.

Pressure is nothing but a force applied onto an area. Pressure in air filled balloon, for example,  is due to "concurrent forces" created by compressed air pushing outward from the center on the balloon. These forces are equal in strength that at the center they clear each other. Thus at the center the pressure is a nonsatble 0.

p=F/A \n\nSo, you have the pressure of the atmosphere pluss the weight of the water above you.  Which is usually figured as a cylinder.  Hope that helps.

it is the normal force per area...\nyou can visit this site:\nhttp://en.wikipedia.org/wiki/Pressure

Pressure is force per unit area. \n\nThe rest of your question is not clear. \n\nPressure is used to forecast weather. \n\nPressure is used to float boats. \n\nPressure is used to power steam engines. \n\nand so on.

Yes to the first question.\n\nYou have to do like this:\n(ai+bj+ck) ___\n\nIn the ___ you put the vetorial unit. Like: meters, cubic meters, newtons, m/s, etc.\n\n₢

Measurements (In distance I'm assuming) would give you volume.\n\nMass / Volume = Density\n\nIf you have volume & density, you can rewrite the equation:\n\nMass = Volume * Density

Pressure= Force/Area\n4.31 N/ 5.07 x 10^ -5 m^2 =.000219 or 2.19 X 10^ -4 N/m^2= P...\nif I remember correctly... I think you also have to take into consideration the  force of gravity (gravitational constant) equal to 9.80 m/s^2 that is acting on the syringe (pushing down).

1 Bar is defined as 14.5 PSI (pound-force per square inch). Standard atmospheric pressure is measured at sea level and some standard temperature, and is taken as 14.7 PSI.  The BAR scale uses the 14.5 PSI as the standard sea level pressure.  So 2 bar = 29 psi, where 2 standard atmospheres would equal 29.4 psi.  The errors are small at pressures near the standard 1 atmosphere as 14.7 PSI.  \n\nSteam is not really important to the question of pressure.  Pounds per square inch applies to liquids, solids, and gases.

kPa/L\n\n(I presume 'L' is litre?)\nI don 't know what quantity this is (pressure per unit volume?) but anyway crunching the numbers:\n\n1Pa=1N/m^2 or: = 1kg m/s^2*m^2 = 1kg /m*s^2\nand 1 L = 0.001 m³ \n\nSo: 1kPa/L = (10^3*0.001) N/m^2*m³\n= N/m^5\n\n(Please tell us what the quantity was?)

Use:\n\npressure = density x height x g\nwhere g = 980 cm/s^2\n\nfor each liquid.  the answer (in dynes) will be the sum of the two pressures.

Pressure is force divided by area.You can use various units of pressure. One is Pascals. A pascal is 1 Newton per squared meter (N/meter^2).\n\nSince you have 125 cm-squared you need to convert to squared meters:\n\n125cm^2 x (1m^2/10,000cm^2)= .0125 m^2, area\n\nA Newton is kg x 9.8=75Kgx9.8= 735 Newtons\n\n735N/.0125m^2= 58,800 Pascal
