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).
Distilled 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. Determine the thermal and hydraulic performance of the heat exchanger with the specified
number of plates.…
