Explanation Given: The diameter of the hose ( d ) is 2 in. The average velocity of the water at point C ( V C ) is 50 ft/s . Calculation: Consider the water is incompressible and inviscid and the steady flow state and water in the pump is control volume. The point B and C are exposed to atmosphere, so the pressure at these points is zero. p B = p C = 0 Water is drawn from large reservoir so the velocity at point V B = 0 . The datum is passed through point B , so the datum levels are, z B = 0 z C = 4 ft − 20 ft = − 16 ft The head losses are negligible. h L = 0 Write the Bernoulli's equation between point B and C . p B γ w + V B 2 2 g + z B + h pump = p C γ w + V C 2 2 g + z C + h turb + h L 0 + 0 + 0 + h pump = 0 + ( 50 ft/s ) 2 2 ( 32

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

100 As a spring is heated, its spring constant decreases. Suppose the spring is heated and then cooled so that the spring constant at time t is k(t) = t sin + N/m. If the mass-spring system has mass m = 2 kg and a damping constant b = 1 N-sec/m with initial conditions x(0) = 6 m and x'(0) = -5 m/sec and it is subjected to the harmonic external force f (t) = 100 cos 3t N.

Two springs and two masses are attached in a straight vertical line as shown in Figure Q3. The system is set in motion by holding the mass m₂ at its equilibrium position and pushing the mass m₁ downwards of its equilibrium position a distance 2 m and then releasing both masses. if m₁ = m² = 1 kg, k₁ = 3 N/m and k₂ = 2 N/m.

Two large tanks, each holding 100 L of liquid, are interconnected by pipes, with the liquid flowing from tank A into tank B at a rate of 3 L/min and from B into A at a rate of 1 L/min (see Figure Q1). The liquid inside each tank is kept well stirred. A brine solution with a concentration of 0.2 kg/L of salt flows into tank A at a rate of 6 L/min. The diluted solution flows out of the system from tank A at 4 L/min and from tank B at 2 L/min. If, initially, tank A contains pure water and tank B contains 20 kg of salt.
