The formulas to calculate Casing Dimensions are:

\[ Hc = 2.2 \cdot D \]

\[ Bc = 2.2 \cdot D \]

\[ Wc = W + \frac{D}{4} \]

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.).
