Which of the following is not an assumption for an ideal fluid flow for which Bernoulli's principle is valid

Assertion: An ideal fluid is flowing through a pipe. Speed of fluid particles is more at places where pressure is low. Reason: Bernoulli's theoren can be derived from work-energy theorem.

The force of viscosity is

A viscometer (an instrument used to study characteristics of a non-ideal fluid) consists of a flat plate and a rotating cone. The cone has a large apex angle and the angle theta shown in figure is very small (typically less than 0.5^(@) ). The apex of the cone just touches the plate and a liquid fills the narrow gap between the plate and the cone. The cone has a base radius R and is rotated with constant angular speed omega . Consider the liquid to be ideal and take its coefficient of viscosity to be eta . Calculate the torque needed to drive the cone.
