The Construction Calcs: 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 : One Section - Asphalt : Two Sections - Asphalt : Three Sections - Concrete Bags - Concrete Footings - Concrete Rectangle - Concrete Sono Tube - Drywall - Roofing NOTE: In this app a Ton is exactly 2,000 lbs. 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. This app features: • Send your calculations or conversions by email • Universal App (iPhone and iPad) • Fast app switching • Automatically Saves Your Inputs • Latest version of iOS is supported • All iPhone screens are supported No network connectivity required.
