Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will
increase
decrease
remain unchanged
data insufficient to predict relative pressure drop.

The Pressure drop is directly proportional to the viscosity as in the Ergun equation.
So viscosity decreased, the pressure drop will be decreased.
