The formulas to calculate Casing Dimensions are:

$$Hc = 2.0 \cdot D$$

$$Bc = 1.6 \cdot D$$

$$Wc = W + 0.16 \cdot D$$

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.).
