Batching, Mixing, Transporting, and Handling Concrete

mixing uniformity within a batch of ready mixed concrete are given in ASTM C 94 (AASHTO M 157). Structural low-density concrete can be mixed the same way as normal-density concrete when the aggregates have less than 10% total absorption by mass or when the absorp-tion is less than 2% by mass during the first hour after immersion in water.

Flow Rate Calculator - Calculate the flow rate of a pipe

Flow Rate Calculator. Easily calculate the volumetric flow rate of a pipe (a.k.a. discharge rate) given its dimensions and either a pressure difference between its ends or the velocity of the liquid or gas flowing through it. The flow rate calculator can also calculate the mass flow rate of a fluid given its density is known. Input and output support metric and imperial measurement units.
