Answer / saparihar
In dead weight tester,
we put the weight on the weight stand of dead weight tester
putting weight is reference weight which is to be calibrate
and further we applied pressure by moving piston ,when
applied pressure and reference weight(Pressure)is equal at
this condition reference weight willbe zero(Dead).
therefore it is called dead weigh tester.

Answer / gayathri
A deadweight tester (DWT) is a calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston.
The formula to design a DWT is based basically is expressed as follows :
p = F / A [Pa]
where :
p : reference pressure [Pa]
F : forca applied on piston [N]
A : effective area PCU [m2]
