Chapter 8, Problem 8.72P

Water flows in a 1.2-m-diameter finished concrete pipe so that it is completely full and the pressure is constant all along the pipe. If the slope is So = 0.0073, (a) determine the flowrate by using open-channel flow methods. Compare this result with (b) that obtained using the pipe flow methods of Chapter 8 (Use Colebrook formula, Table 8.1, Table 10.1 and assume that Re > 10º). (a) Q = i (b) Q = i m³/s m³/s

Two channels and two plates are used to formthe column section shown. For b = 200 mm,determine the moments of inertia and theradii of gyration of the combined section withrespect to the centroidal x and y axes.For the section of problem, determine thefirst moment of the upper plate about thecentroidal x-axis

Determine by direct integration the moment of inertia of theshaded area at right with respect to the x axis shown.  Determine by direct integration the moment of inertia of theshaded area of the figure with respect to the y axis shown.

For the following MATLAB code, I need to answer a few questions. Can you identify the curves as elliptic functions? Which curves reflect the sn, cn, and dn functions?From the curves, determine the maximum amplitudes and the period corresponding toeach angular velocity component.   clc; clear all;   I = [500; 125; 425]; w = [0.2; 0.1; 0.2]; rev = 0:0.01:10; C = eye(3);   % Using ode45 to integrate the KDE and DDE options = odeset('RelTol',1e-9,'AbsTol',1e-9); result = ode45(@K_DDE, rev, [w; I; C(:)], options); v = result.x;       % Extracting information from the ode45 solver w = result.y(1:3, :); C_ode = reshape(result.y(7:end, :), [3,3,length(v)]);     plot(v, w) xlabel('rev') ylabel('w (rad/s)') legend('w1', 'w2', 'w3')         % Functions function dwCdt = K_DDE(~, w_IC)   % Extracting the initial condtions to a variable w = w_IC(1:3); I = w_IC(4:6); C = reshape(w_IC(7:end), [3, 3]);     I1 = I(1); I2 = I(2); I3 = I(3);   K1 = -(I3-I2)/I1; K2 = -(I1-I3)/I2; K3 = -(I2-I1)/I3;   %…

please show a drawing/image and explain how to properly do the question. thanks

7.4 Impeller viscometer The rheology of a Penicillium chrysogenum broth is examined using an impeller viscometer. The density of the cell suspension is approximately 1000 kg m³. Samples of broth are stirred under laminar conditions using a Rushton turbine of diameter 4 cm in a glass beaker of diameter 15 cm. The average shear rate generated by the impeller is greater than the stirrer speed by a factor of about 10.2. When the stirrer shaft is attached to a device for measuring torque and rotational speed, the following results are recorded. Stirrer speed (s¹) Torque (Nm) 0.185 3.57 × 10-6 0.163 3.45 × 10-6 0.126 3.31 x 10-6 0.111 3.20×10-6 Can the rheology be described using a power-law model? If so, evaluate K and n.
