Consider the incompressible flow of a fluid through a nozzle as shown. The area of the nozzle is given by A = A0(l − bx) and the inlet velocity varies according to U = U0(0.5 + 0.5cos ωt) where A0 = 5 ft2, L = 20 ft, b = 0.02 ft-1, ω = 0.16 rad/s and U0 = 20ft/s. Find and plot the acceleration on the centerline, with time as a parameter.

- Please help me with this fluid mechanics question! Thank you!! :) A 1967 Harley-Davidson Shovelhead motorcycle uses a ventruri-carburetor to mix air and fuel for combustion. The venturi reduces the pressure to draw fuel from a reservoir chamber and to mix with the airstream as shown in the figure. The energy loss of the metering line is given by hL= (K*V^2)/2where K = 6.0 and V is the fuel velocity in the metering line. Assume that the air is an ideal fluid (68°F). Calculate the mass flux of air and the mass flux of fuel. Hint: Assume the air intake velocity is negligible.arrow_forwardA brand of toothpaste is made using a mixture of white and red paste. During the manufacturing process, both pastes are pumped through a pipe, with the red paste lying in the center of the pipe, as shown in Figure Q2. The pipe has an internal radius, R2, and the segment of red paste has a radius R1. The flow is found to follow the Poiseuille equation, i.e. 1 dp u(r) = -- 4µdx (R²2-²) Where u is the viscosity of the paste and dp dx is the pressure gradient. The total flow of toothpaste through the pipe is Qtot, and the flowrate of the red paste is Qred. The toothpaste has a density of p = 1200 kg/m3, and a viscosity of 0.03 Pa.s. The pipe has a radius R2 = 5 cm and a length L = 2 m. a) Find an expression for the flowrate of the red toothpaste.
