A ring-shaped seal, made from a viscoelastic material, is used to seal a joint between two rigid pipes. When incorporated in the

joint, the seal is held at a xed compressive strain of 0.2. Assuming that the seal can be treated as a Maxwell model, determine the time before the seal begins to leak under and internal uid pressure of 0.3 MPa. It can be assumed that the relaxation time 0 of the material is 300 days and the short-term (instantaneous) modulus of the material is 3 MPa.

Bas_tet [7]

Answer:

True strain = 3.7704

Explanation:

Strain is the measure an object that is stretched or deformed. This occurs when a force is applied to an object. Strain deals mostly with the change in length of the object. Strain = Δ L /L = Change in Length over the original Length:

Volume Constancy :

ΔL/L0=A0/ΔA=(D0/ ΔD)=(25mm/0.75mm)^2

ΔL/L0=44.4

Engineering strain:

Engineering strain =ΔL-L0/L0=ΔL/L0-1

Engineering strain =44.4-1=43.4

True strain, ε=In(ΔL/L0)=In(43.4)=3.7704

Note that strain has no unit, so the True strain = 3.7704

vaieri [72.5K]

Answer:

The answer is "83.98, 1889.195, and 1889.195"

Explanation:

Given value:

\bold{P_{4}=2.34 \ kPa}

In point a:

The value of h_{f4}=83.915 \ \ \frac{Kj}{kg}\\

V_4=0.001002 \ \  \frac{Kj}{kg}\\\\U_4= 83.98 \ \ \frac{Kj}{kg}\\\\

In point b:

calculating heat leaves formula= h_3-h_{f4}

                                                      = 1973.11-83.915\\\\= 1889.195 \ \ \frac{KJ}{kg}

In point c:

calculating Heat transfer rate formula=m(h_3-h_4)

                                                              = 1(1889.195)\\\\                                     = 1889.19 \ \ kw.
