Asphalt & Concrete & Drywall & Roofing

Available in the App StoreThe Asphalt & Concrete & Drywall & Roofing app consists of calculators and solvers to help contractors and sales people estimate costs, sizes, and materials amount as well as prices.

– Asphalt
– Concrete Bags
– Concrete Footings
– Concrete Rectangle
– Concrete Sono Tube
– Drywall
– Roofing

Also, featuring fuel injector calculators

– Fuel Injector Size Calculator
– Fuel Injector Flow Calculator
– Fuel Injector Horsepower Calculator
– Tire Diameter Converter
– Flow Rate Conversion
– Temperature Conversion

The Fuel Injector Size Calculator assists in selecting the correct size injector for your engine. Simply enter the engine horse power, the brake specific fuel consumption (BSFC), the number of injectors to be used, the maximum duty cycle, and the system fuel pressure in pounds per square inch. The calculated injector flow rate is computed in both pounds of fuel per hours (lbs/hr) and cubic centimeter per minute (cc/min).

The Fuel Injector Flow Calculator computes improved fuel pressure in both lbs/hr and cc/min. Simply enter the current fuel pressure at the injector inlet (PSI), the anticipated/improved fuel pressure at the injector inlet (PSI), and the fuel injector fuel flow rating in pounds of fuel per hours (lbs/hr) or cubic centimeter per minute (cc/min).

The Fuel Injector Horsepower Calculator assists in selecting the correct size injector for your engine. Simply enter the Brake specific fuel consumption (BSFC), the number of injectors to be used, and the injector flow rate in either pounds of fuel per hours (lbs/hr) or cubic centimeter per minute (cc/min). Outputed is the horsepower potential.

Relative Humidity Calculator & Temperature Converter (Celsius, Fahrenheit, Kelvin)

Available in the App Store

Features Fetching current weather conditions over the network and provides a 7 day forecast.

* Featured by Apple in ‘What’s Hot’ in the United States, United Kingdom, and Italia under iPad > Weather
* Featured by Apple in ‘What’s Hot’ in the Italia and United Kingdom under iPhone > Weather

The temperature converter converts between Celsius, Fahrenheit and Kelvin.

Relative humidity may be defined as the ratio of the water vapor density (mass per unit volume) to the saturation water vapor density, and in the case of this iPhone App it is expressed as a percentage. The air temperature and dew point can be entered as Fahrenheit or Celsius.

This app features:

• Send your calculations or conversions by email
• Universal App (iPhone, iPod Touch, and iPad)
• iOS 5 & 6 are supported
• iPhone 5’s 4 inch screen and the original 3.5 inch screen are supported
