The formulas to calculate Casing Dimensions are:

\[ Hc = 1.4 \cdot D \]

\[ Bc = 1.35 \cdot D \]

\[ Wc = W + 0.1 \cdot D \]

Where:

• \(Hc\) is the height of the casing (in.).
• \(Bc\) is the breadth of the casing (in.).
• \(Wc\) is the width of the casing (in.).
• \(D\) is the diameter of the impeller (in.).
• \(W\) is the width of the impeller (in.).
