The ANSWER of the equation using MATLAB.

Answer to Problem C.6E
y=0.5−10=−9.5.
Explanation of Solution
Given:
y=0.5−w,wherex=[2648210694].
x=[2648210694] and w=[56789].
Calculation:
Using matrices we can determine value of y=0.5−w, before we must understand matrices.
It most popular applications for engineering curricula it like a
A=[957864421].
Every matrix has certain size depending on its number element exist in the column and rows, such as in above example size of A= 3×3 means three rows and three columns. The command which give size of matrix is size, for example it can be written in MATLAB command format “size(A)” then it would return “3 3” for above matrix.
We can find a position of each element in matrix as first column and first row means we could written as a11 and the value would be 9.
Suppose we require to take element such a1.1, a1.2, a2.1, and a22, and many more then we should enter as
now come to given problem,
By using MATLAB, multiply matrices of same size
Multiplying first row of first matrices and second matrices of first row then it results 10.
So
Some common method for multiplying two matrices shown below.
Conclusion:
MATLAB follows the matrices rules so we must write in matrix form.

- Using the moment-area theorems, determine a) the rotation at A, b) the deflection at L/2, c) the deflection at L/4. (Hint: Use symmetry for Part a (θA= - θB, or θC=0), Use the rotation at A for Parts b and c. Note that all deformations in the scope of our topics are small deformation and for small θ, sinθ=θ).arrow_forwardDistilled water is being cooled by a 20% propylene glycol solution in a 1-1/U counter flow plate and frame heat exchanger. The water enters the heat exchanger at 50°F at a flow rate of 86,000 lbm/h. For safety reasons, the water outlet temperature should never be colder than 35°F. The propylene glycol solution enters the heat exchanger at 28°F with a flow rate of 73,000 lbm/h. The port distances on the heat exchanger are Lv = 35 in and Lh = 18 in. The plate width is Lw = 21.5 2 in. The plate thickness is 0.04 in with a plate pitch of 0.12 in. The chevron angle is 30° and the plate enlargement factor is 1.17. All ports have a 2 in diameter. The fouling factor of the propylene glycol solution can be estimated as 2 ×10−5 h-ft2-°F/Btu. a. Determine the maximum number of plates the heat exchanger can have while ensuring that the water outlet temperature never drops below 35°F. b.

The shell has a diameter of 27 in and a length of 16ft. The tubes in the heat exchanger are ¾-in 15 BWG tubes on a 1-in triangular pitch. The purposeof this problem is to investigate how the number of baffles impacts the heat transfer and thepressure drop on the shell side of the heat exchanger. Calculate the shell-side convective heattransfer coefficient and pressure drop for the case where the heat exchanger has 10 baffles. Repeatthe calculation for 20 baffles. Then determine thea. Ratio of the shell-side convective heat transfer coefficient for the 20-baffle heat exchangerto the 10-baffle heat exchangerb. Ratio of the shell-side pressure drop for the 20-baffle heat exchanger to the 10-baffle heatexchangerc.
