Pump Calculus app for iPhone and iPad

Pump Calculus is a set of practical tools related to pumps, specially designed for irrigation, gardening and industry.
• Calculate hydraulic and electrical power pumps in HP and Kw.
• Calculate energy costs by two different or complementary ways. It answers
questions such as:
• If low pressure at 30 ft as saving them in a year?
• The annual savings in one hectare (or acre) of orange if I reduce 40 ft
pressure?
Power relates to:
• Flow.
• Total head
• Efficiency.
Any variable calculated knowing the other.
Power relates to:
• Current.
• Voltage.
• Efficiency.
• cos φ
Any variable calculated knowing the other.
Calculate energy costs in two complementary ways:
• When you know power and number of hours of operation.
• When you know total volume and total head
