- A jet impinges on a splitter block. The incoming jet is horizontal and has a flow rate of Q1 = 8000 cm³/s and a cross-sectional area of A1 = 40 cm². The block splits the jet in to two smaller jets. One is deflected upward by 45°, and has a flow rate of Q2 = 6000 cm3/s and a cross-sectional area of A, = 30 cm?. The other jet is deflected downward by 45°, and has a flow rate of Q3 = 2000 cm³/s and a cross-sectional area of A3 = 10 cm². You may assume that the pressure everywhere is equal to atmospheric pressure, and the density of the fluid is 1000 kg/m³. Find the horizontal momentum flux in, or in Q,= 6000 cm³/ A2= 30 cm2 Q,= 8000 cm³/s . %3D e = 45° e = 45° A,= 40 cm² %3D A3= 10 cm² Q3= 2000 cm3/sDerive an expression for the shear stress acting on the top plate Tw. Q' is the flow rate per unit width (i.e. has units of m^2/s). Express Q' in terms of Tw. When the flow rate per unit width is Q'=1.2*(10^-4) m^2/s, the gap between the plates is 5mm, he device estimates the shear stress at the top wall to be -0.05 Pa. Estimate the viscosity of the fluid. When the tests are repeated for blood ample, different estimates of viscosity are found for different flowrates. What does this tell you about the viscosity of the flow? Use appropriate terminology. As the pressure gradient is increased, at a certain point the measurements cease to be reliable. Using knowledge of fluid mechanics, give a possible reasonfor this. Use appropriate terminology.C2.
