The Bulk modulus for an incompressible liquid is

zero

unity

infinity

between O and 1

Solution

infinity

Bulk modulus:- The ratio of hydraulic stress to hydraulic strain called bulk modulus. It is denoted by B.

B = $\frac{- p}{\frac{∆ V}{V}}$ ......(i)

The negative sign indicates that with an increase in pressure, a decrease in volume occurs. That is p is positive, ΔV is negative

For incompressible fluid, ΔV = 0

⇒ Equation(i) becomes

B = $\frac{- p}{0}$ = infinite
