A streamlined body is defined as a body about which

A jet of water (area $${A_j},$$ velocity $${V_j},$$ density $$\rho $$ ) impinges horizontally on a curved vane which deflects the jet through $${60^0}$$ upwards. If the vane travels horizontally at a speed $$'u'$$ find
(a) the force experienced by the vane, and
(b) the power developed by the vane.

When a Pitot-static tube is immersed in a water stream (density $${\rho _w}$$), the differential head measured by a mercury (density $${\rho _m}$$ manometer is $${h_m}.$$ What is the velocity of the water stream?

Consider the saline drip bottle shown. If $$\rho $$ is the density of saline, find
(a) Pressure at $$A,$$
(b) The velocity of flow of saline through the tube. (Neglect viscous losses in tube). Atmospheric pressure $${P_{atm}}.$$
