To determine The discharge of water through the drainpipe. Explanation Given: The pressure at point B is 40 kPa . The elevation of point B from point A is 5 m . Calculation: Calculate the pressure at B . p B = ρ k e g h B C = ( 1.58 slugs/ft 3 ) ( 32.2 ft/s 2 ) ( 1.5 ft ) = 76.314 lb/ft 2 Consider that the water is incompressible and inviscid. Apply the Bernoulli’s equation between the points B and A . p B ρ o + V B 2 2 + g z B = p A ρ o + V A 2 2 + g z A (I) The datum reference is set at the point A . z A = 0 z B = 5 m Consider that the water is released from the large reservoir ( B ). The water in the reservoir is stationary. Thus, the velocity at point B is zero. V B = 0 The point A is exposed to atmosphere, the pressure at this point is equal to atmospheric pressure, and thus it can be neglected. p A = 0 Substitute the respective values in Equation (I).

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.

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. A 6 L/min 0.2 kg/L x(t) 100 L 4 L/min x(0) = 0 kg 3 L/min 1 L/min B y(t) 100 L y(0) = 20 kg 2 L/min Figure Q1 - Mixing problem for interconnected tanks Determine the mass of salt in each tank at time t≥ 0: Analytically (hand calculations) Using MATLAB Numerical Functions (ode45) Creating Simulink Model Plot all solutions on the same graph for the first 15 min. The graph must be fully formatted by code.

ased on the corresponding mass flow rates (and NOT the original volumetric flow rates) determine: a) The mass flow rate of the mixed air (i.e., the combination of the two flows) leaving the chamber in kg/s. b) The temperature of the mixed air leaving the chamber. Please use PyscPro software for solving this question. Notes: For part (a), you will first need to find the density or specific volume for each state (density = 1/specific volume). The units the 'v' and 'a' are intended as subscripts: · kgv = kg_v = kgv = kilogram(s) [vapour] kga = kg_a =kga = kilogram(s) [air]
