The diameter and volume of shrinkage in copper and iron needs to be compared. Concept Introduction: Shrinkage is a type of defect occurred in the cast component during solidification of molten metal. The material shrinks during solidification depending on the duration of cooling. Shrinkage volume of material can be calculated as, V shrinkage = 4 3 π r 3 × % shrinkage 100 Where, r = radius of the material V shrinkage = volume of shrinkage

Chapter 9, Problem 9.75P

Interpretation Introduction

Interpretation:

The diameter and volume of shrinkage in copper and iron needs to be compared.

Concept Introduction:

Shrinkage is a type of defect occurred in the cast component during solidification of molten metal.

The material shrinks during solidification depending on the duration of cooling.

Shrinkage volume of material can be calculated as,

Vshrinkage=43πr3×%shrinkage100

Where, r = radius of the material

Vshrinkage = volume of shrinkage

Ideal gas Problems 3-1 The molecular weight of carbon dioxide, CO2, is 44. In an experiment the value y for CO2 was found to be 1.3. Assuming that CO2 is a perfect gas, calculate the gas constant, R, and the specific heats at constant pressure and constant volume, Cp, Cv (0.189 kJ/kg.K; 0.63kJ/kg.K; 0.819kJ/kg.K) 3-2 Oxygen, O2, at 200 bar is to be stored in a steel vessel at 20°C the capacity of the vessel is 0.04m³. Assuming that O₂ is a perfect gas, calculate the mass of oxygen that can be stored in the vessel. The vessel is protected against excessive pressure by a fusible plug which will melt if the temperature rises too high. At what temperature must the plug melt to limit the pressure in the vessel to 240bar?
