Evaluate the partial derivatives of the shape functions at ψ = 1/4 and η = 1/2 of a quadrilateral element shown in Figure 3.32 assuming that the temperature is approximated by
(a) Bilinear
(b) Quadratic interpolating polynomials.
40-m long section of a horizontal steam pipe of 6-cm in outside diameter has a surface temperature of 170c and
Determine, the exit stagnation temperature of the air and the poly tropic efficiency of the compressor. Assume for air that γ = 1:4.
The velocity of plane B relative to plane A can be expressed in the following form vb/a = Mi+Nj M i is the x-component of the velocity of plane B relative to plane A. what is the value of M, in km/h ?
A system consists of liquid nitrogen in equilibrium with nitrogen vapor. How many phases are present? The system undergoes a process during which all of the liquid is vaporized. Can the system be viewed as a pure substance during the process? Explain..
What in your refuse might have been reusable (as distinct from recoverable), and if you had reused it, how much would this have reduced the refuse?
when a force is transferred to another point of the body indicate which of the following quantities remain unchanged
In Example 16.7, it turns out that the new process does not save one cent per unit. It only saves 0.3 cents per unit. What is the new BEP, and was it worth the expense to make this improvement?
