A new design of nitrogen charged accumulator, for use in a hydraulic circuit, is being factory tested for certification purposes.(http://www.accumulators.co.uk/). The following data has been collected by a technician:
o Gas volume: V = 0.8 m3
o Gas pressure: p = 160 kPa
o Compression index: n = 1.4
o Pressure/volume relationship: pV ⁿ = C
o Work done =
i. Evaluate C.
ii. Calculate the work done in compressing the nitrogen from 0.8 m3 to 0.6 m3 using:
o integral calculus
o Simpson’s rule
o the mid-ordinate rule.

Perform three iterations of the inverse power method to obtain the smallest eigenvalue in magnitude of the matrix [{2,5},{3,6}].
Take appropriate initial approximation to the eigenvector.
Set up a Gauss Seidel iteration scheme for the system of equations given below
[{6,0,1/2},{1/2,2,-1},{3,1,0}] [{x_1},{x_2},{x_3}]=[{1},{-1},{2}].
How many iteration are required to reach the accuracy of 5×10^(-4) ?
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
