1. It is a type of flow where the fluid is assumed ideal with the viscosity of zero.

2. In compressible flow, it is a limiting condition which occurs when the mass flow rate will not increase with a further decrease in the downstream pressure environment while upstream pressure is fixed.

d. Rise of water in capillary tubes reduces with the increasing diameter of capillary tubes

4. Pick out the wrong statement.
a. Human blood is a Newtonian fluid
b. A Newtonian fluid obeys Newton’s law of cooling
c. For a non-Newtonian fluid, a straight line passes through the origin in a plot between shear stress and
