If pressure is given by P=A+B by t and -c by D +v where t and v are time and velocity respectively then find dimensional formula of A, B,C&D.

Please write your equations in an acceptable standard way. Do not use words like "and" and "by" in the equation.

Do you mean

P = A + B/t - C/(D+v) ?

What do you mean by a "dimensional formula?"

In the equation I have written,

A has dimensions of pressure

B has dimensions of (pressure)*time

C has dimensions of (pressure)/(velocity)

D has dimensions of velocity

yes i mean the above equation which u have written P=A+B/T-C/D+V.

The expression which shows how and which of the base quantities represent the dimensions of a physical quantity is called the dimensional formula.

M - mass,

L - length,

T - time

Pressure P

Pa= N/m² = kg•m/s²m²=kg/m•s² =M•L^-1•T^-2 ,

A = M•L^-1•T^-2 ,

B= M•L^-1•T^-1,

C = M•L^-2•T^-1,

D =L•T^-1.

i have not understood how n/m square it comes kgm/s2m2 and the cap symbol.

Newton is the unit of force

F= ma =>

m –> kg

a-> m/s²

N = kg•m/s² =M•L•T^-2
