[12263 leg] of heat supplied it the Steam is to oAnswer with True or False of the following question: (7M 1. Water flows steadily down a vertical pipe of constant cross section. Neglecting friction, according to Bernoulli's equation, velocity decreases with height. 2. A liquid in an open right circular cylinder is given rigid body rotation about the axis of the cylinder. The pressure distribution in any vertical plane is uniform. 3. A curved surface is submerged in a static liquid. The horizontal component of pressure force on it is equal to the pressure force on a vertical projection of the surface. 4. A U-tube manometer measures the difference in total energy between two points.pls ans asap Water flows at 0.07 cubic meter per second through a pipe. A horizontal venturi meter with throat diameter of 150-mm was used to measure the velocity inside the pipe. Based on manometer reading, the differential gauge is deflected 1.2 meter.
