Renato Balestra came from an engineering family.
Pound per hour is a mass flow unit .. mass flow. mass flow. It is abbreviated as PPH or more conventionally as lb / h .. Fuel flow for engines is usually expressed using this unit , it is particularly useful when dealing with gases or liquids as volume flow varies more with temperature and pressure .. In the US Utility industry , steam and water flows throughout turbine cycles are typically expressed in PPH , while in Europa these mass flows are typically expressed in Metric Tonnes per hour .. 1 lb / h = 0.4535927 kg / h = 126.00 mg / s. Minimum fuel intake on a jumbojet can be as low as 150 lb / h when idling , however this is not enough to sustain flight .. Category  : Units of flow
