This Demonstration calculates and displays the volumetric and mass flow rates of a liquid maintained at a constant height in a tank as a function of the liquid's height and density , the drain pipe's diameter and the discharge (orifice) coefficient .... cooling coil condensate can be calculated by the following formula cc condensate (gpm)=(4.5/500)*cfm*change in humidity ratio of the air(lb/moister/lb of dry air).

28/04/2009 · I have a very simple problem, but I am trying to gain confidence in the calculations for drain down time and flow rate for a free-flow tank drain situation. I have used free calculators at www.freecalc.com and www.e-funda.com , and I calculated the results by hand from my fluid mechanics notes. the hand calculation formula i used is... APPENDIX A ROOF DRAIN SIZING METHOD (APPENDIX A IS FOR INFORMATIONAL PURPOSES ONLY) walls. This method converts the roof area to an equivalent roof area for a 4-inch rate of rainfall so that Table 1108.1 and Table 1108.2 can be used as printed. The method described in 1108.2.2 converts Table 1108.1 and Table 1108.2 to tables for the rate of rainfall specified for the area. A101.1 …

Then, you may have to calculate the discharge flow first. You can figure out the drain pipe length, number of fittings, shut off valve, and even the elevation difference, then use Hazen-Williams formula to figure out the flow and Manning's formula to figure out the floor drain capacity. how to find router ip address android This rate will let you know how much area in square feet the bed needs to cover for draining water to infiltrate, or absorb into, the soil rather than pooling on or running off the area.

Formula for calculating rate drain. Ask Question 1. A question which I am having difficulty with is: A tank is 3/4 full. Fillpipe A can fill the tank in 12 min. Drainpipe B can empty the tank in 8 min. If both pipes are open, how long will it take to empty the tank? how to find out wheb ginger tea is expired Smith warns that the roof drains should be emptying into larger-diameter storm drains to avoid backpressure or hydraulic "jump" that could seriously impair the drain flow rates in the system. Smith used a multiplier of 0.0104 in these calculations to convert inches of rain fall per hour into gallons of water per minute per square foot, resulting in the following formula for calculating roof

## How To Find Drain Rate

FLUID AND PIPING DATA; None of these fields can be left blank, enter 0 if necessary Nominal Pipe Size:

- Condensate drains carry away the water, usually into the sewer. Instead of wasting it, more and more buildings, especially in parts of the country with hot, humid summers, are capturing that condensate for …
- To find the DESIGN condensate drain, one needs to know the design inlet and outlet air conditions (precisely the moisture content and air flow rate). The difference between inlet and outlet conditions of the moisture content gives the condensate flow rate. Then based on the standards from ASHRAE
- The first step in sizing a roof drain is to calculate the surface area of the roof that the drains will be covering as well as the average hourly rainfall rate at the building location.
- The Drainage Calculators help users address common calculations for agricultural subsurface (tile) drainage design. Tools Pipe sizing. Pipe Size to Area Drained: Calculate …
