What is the purpose of nondestructive examination or testing?
Expert Solution & Answer

To determine
The purpose of nondestructive examination or testing.
Explanation of Solution
Non-destructive testing (NDT) is the method of analysis that is applied in the large scale industry to examine the properties of material, structure of the component and surface
defects including the welding defects. It is also called as Non-destructive examination method.
The purpose of nondestructive testing are as follows:
- One of the major purpose for the adoption of non-destructive testing is that extraction of usefulness of the components for the future service. In other words, the components possesses long serviceability.
- During the non-destructive testing there is no damage caused to the component or the product.
- This method is also cost effective as the overall testing cost is much lesser.
- The quality obtained by this method is much good as well as the damage free products are manufactured.
- Another purpose for the adoption of this method is to achieve product reliability.

Q1. A The gas-turbine cycle shown in Fig. is used as an automotive engine. In the first
turbine, the gas expands to pressure Ps, just low enough for this turbine to drive the
compressor. The gas is then expanded through the second turbine connected to the
drive wheels. The data for the engine are shown in the figure, and assume that all
processes are ideal. Determine the intermediate pressure Ps, the net specific work
output of the engine, and the mass flow rate through the engine. Find also the air
temperature entering the burner T3 and the thermal efficiency of the engine.

I need to find m in R = mD from the image given. Do you really need to know what R and D is to find R. I was thinking geometrically we can find a relationship between R and D. D = R*cos(30). Then R = mD becomes m = R/D = 1/cos(30) = 1.1547. Is that correct?
Q1] B/ (16 Marks) To produce a lightweight epoxy part to provide thermal insulation. The available
material are hollow glass beads for which the outside diameter is 1.6 mm and the wall thickness is 0.04
mm. Determine the weight and number of beads that must be added to the epoxy to produce a 0.5 kg of
composite with a density of 0.65 g/cm³. The density of the glass is 2.5 g/cm³ and that of the epoxy is
1.25 g/cm³.
