Plumbing & HVAC Calculators

Posted by on August 4, 2010 Comments Off on Plumbing & HVAC Calculators

Available in the App Store

The Plumbing & HVAC Calculators & Converters app is good for reference, educational, and small projects.

Calculators

1. Weights (Ounces, Grams, Pounds, Tons US, Kilograms, Tons UK, and Tonnes
2. Virtual Airflow (US Units)
3. Virtual Airflow (Metric Units)
4. Reynolds Number for Metric
5. Reynolds Numberfor US / Imperial

The Virtual Airflow & Reynolds Number calculators are designed to give related and relevant information about the amount of air in a defined area, and the size air handler or fan required to move it in a given amount of time. The air movement can be from a heater, AC unit, chiller, refrigeration unit, closed fan unit or cooler (swamp cooler or evaporative cooler) into the area, or from an exhaust fan moving the air out of the area.

For the distance calculators enter the area dimensions in feet or meters. Accuracy to the inch or centimeter is not needed. Enter the number of times per hour that you would like total change of the air mass volume in that area. Enter the air flow specification of the air handler (fan) you anticipate using in cubic feet per minute (CFM) or cubic meters per minute. Click on Calculate and the results will be the (air) volume of the area, the amount of time for each volume of air mass change, the total volume of air requiring movement with an hour, the volume air flow of the suggested fan (based on your entries) and the number of fans or air handlers needed if they are of the target size you selected.

A guideline for clear air (especially if filtered) in an area is 4 to 8 complete cycles every hour.

Note: Should not be considered for open fan blade fans in ceilings higher than 12 feet or with fan’s rated or measured in capacity for a room size in square feet rather than cubic feet.

Acre & Area & Acreage Calculator

Posted by on August 3, 2010 Comments Off on Acre & Area & Acreage Calculator


Available in the App Store

* Featured by Apple in ‘What’s Hot’ and ‘New & Noteworthy’ in 80 places.

The Acreage Calculator is designed to supply the number of acres (acreage), square feet, square yards, square inches, square meters, and square kilometers based on the values entered. This is an extremely useful calculator for real estate information.

The word acre is defined as meaning an open field. The acre was approximately the amount of land estimated tillable by one man plowing behind an ox in one day. This explains one definition as the area of a rectangle with sides of length one chain (66 feet) and one furlong (660 feet). In reality, a long narrow strip of land is more efficient to plow than a square plot, since the plow does not have to be turned so often. The word furlong (most commonly used in horse racing) itself comes from the fact that it is one furrow long.

This app features:

• Send your calculations or conversion by email
• Universal App (iPhone, iPod Touch, and iPad)
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs

No network connectivity required.

Torque+

Available in the App Store

The Torque+ app is designed to supply information about the torque using Force and Distance, or Length, in put as Newton-meters, Foot-pounds, Inches, Feet, Yards, or Meters.

Also, there are converters for the motion of the wheel and tire on a vehicle, based on the vehicle’s speed in MPH or KPH, rim diameter, and tire body size. The calculator’s results are the RPM (revolutions per minute) of the tire, the RPS (revolutions per second) of the tire, and the distance traveled per second in meters or feet.

Calculators

– Torque (N-m)
– Torque (Lbs-Ft & N-m)
– Torque Converter between Lbs-Ft & N-m

Converters

– Gauge and Size
– Tire Diameter
– Wheel and Motion

Area Converters

• Square Inches and Shorter Conversion
• Square Feet & Yards & Meters Conversion

Distance Converters

• Inches & Centimeters & Millimeters Conversion
• Feet & Yards & Meters Conversion
• Miles & Kilometers Conversion

Volume Converters

• US/Imperial to Metric Units Conversion
• Metric to US/Imperial Units Conversion
• Inches & Centimeters Volume Conversion
• Feet, Yards, & Meters Volume Conversion

This app features:

• Send your calculations or conversions by email
• Universal App (iPhone, iPod Touch, and iPad)
• iOS 7 is supported
• iPhone 5’s 4 inch screen and the original 3.5 inch screen are supported
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs
