Greenhouse Gases Equivalencies Calculator - Calculations

Apr 28, 2021 · This page describes the calculations used to convert greenhouse gas emission numbers into different types of equivalent units. Go to the equivalencies calculator page for more information. A note on global warming potentials (GWPs): Some of the equivalencies in the calculator are reported as CO 2 equivalents (CO 2 E). These are calculated using GWPs from the Intergovernmental Panel on …

Pump Power Calculation Formula | Specific speed of a

Sep 22, 2018 · Specific Speed of Pump. The specific speed "Nq" is a parameter derived from a dimensional analysis which allows a comparison of impellers of various pump sizes even when their operating similar Q -H range.. The specific speed can be used to classify the optimum impeller design. Specific Speed of pump (Nq) is defined as the speed in RPM at which a geometrically similar impeller …

Whenever possible, avoid the arrangement and erection of batching plants in

Batching, Mixing, Transporting, and Handling Concrete

B = batch liquid density at the average batch temperature, lb./cu. ft. Substituting equation (5) into equation (10) and rearranging into dimensionless form yields: (P Delivered * g c) / ( N 3 * D5 * ρ B) = π 4 * ( W / D ) * ( 1 – k) * tan β 2 (10) The left-hand side of equation (10) is called the power number, N P: N P = (P Delivered * g c) / ( N 3 * D5 * ρ

Plant Engineering | Three steps to size motors

Aug 06, 2019 · A motor's primary job is to continue spinning at a commanded speed regardless of the torque load so it can deliver the necessary amount of mechanical power. The motor must overcome the load's inertia, or resistance to movement, to accelerate to the desired speed, and then maintain it. Not every motor load is the same, however.
