Water is flowing through a long horizontal tube. Let `P_A and P_B` be the pressures at two points A and B of the tube

Water is flowing through a long horizontal tube. Let P_(A) & P_(B) be the pressure at two points A & B of the tube

Water is flowing streamline motion through a horizontal tube. The pressure at a point in a tube is P where the velocity of flow is v. At another point where the pressure is p/2 , the velocity of flow is (density of water = rho )

Water is flowing in streamline motion through a horizontal tube. The pressure at a point in the tube is p where the velocity of flow is v. At another point, where the pressure is p/2, the velocity of flow is [density of water =rho ]

Turpentine oil is flowing through a tube of length I and radius r. The pressure difference between the two ends of the tube is P , the visocity of oil at a distance x from the axis of tube from this relation, the dimensions of viscosity are :
