<td width=”70%” class=”size12pt”>Flow calculator is a small, compact and useful tool which helps the user make very fast flow related calculations .  It is a simple calculation without too many options for users who only want to see what they might expect . The simple interface only contains three text boxes. These text boxes correspond to the inside diameter of the cylindrical pipe, velocity and the volumetric flow rate</td>
</tr>
</table>
Any two quantities when filled in the text boxes can be used to calculate the third one. Inside diameter can be provided in any one two units ie. inches and milimeters. Similarly, velocity can also be provided in any of four units such as inches/second, feets/second, meters/second and centimeters/second. The third quantity can be expressed in any of the units such as cubic feet/sec, cubic feet/min cubic feet/day, US gallon/sec, US gallon/sec, UK Barrels/sec, UK Barrels/sec, US Oil Barrels/sec and US Federal Barrels/sec </td>
