pressure=force/area
force=mass*acceleration
area=lenth*length=L^2
acceleration=velocity/time
=>distance/time/time=L/T^2 or LT^-2
so force=MLT^-2
pessure=force/area
=MLT^-2/L^2
=ML^-1T^-2

Formula For Pressure

2016-09-29 00:52:40 · answer #2 · answered by ? 4 · 0 0

Pressure = force/area
Force = mass * accln = ML/T*T
Area = L*L
Hence pressure = M/L*T*T(remember to write the dimensional formula in indices

The dimensional formula of any physical quantity is the expression for its unit in terms of the base units, that of mass length and time taken as M, L and t respectively.

First express the quantity in terms of basic quantities.
Pressure = force/area.
Force = massx acceleration
Acceleration = Change in velocity/time
Velocity =Change in displacement/time. Area = Lentghx Length

Combining all the above,

Unit of Pressure = Unit of (massx displacement/time xtme/lengthxlength. = M.L/T2/L2 will complete later.

The dimesional formula of pressure is [ M L^-1 T^-2].

Pressure (symbol: p) is the force per unit area applied on a surface in a direction perpendicular to that surface. Mathematically:

P=F/A

where:

P is the pressure
F is the normal force
A is the area.

Pressure is force applied per unit area
so
Dimen. Form. = M1 L-1 T-2
P= F/A
F= M1 L-1 T-2
A= L2
P= M1 L-1 T-2

Pressure on a mass structure is defined as Energy per Unit volume. The results of dimensional analysis is as folows;
Energy = Mc^2
Volume is 4.2 R^3
Dimensions of energy =Kg x meter^2/seconds ^2
Dimension of volume = Meter ^3
Taking the ratio of the dimensions we get Kg /meter- seconds^2.
In SI units its called a Pascal.

h is length (rho) is density--mass over length^3 r is length g is an acceleration--length per time^2 Multiply that all out, lengths cancel, and what is left is mass per time^2. Force is mass times acceleration or mass * length / time^2. So our result is a force over a length--just what you wanted!

We know pressure is Force per unit Area.
force = [ML/T2]
area = [L2]
Therefore pressure = [M/LT2] :-)
