Pump efficiency and its formula

Refers to the effective pump power and shaft power ratio. η = Pe / P Pump power usually refers to the input power, that is, the prime mover to the shaft power, it is also known as shaft power, with P said. Effective power is: pump head and mass flow and acceleration of the product of gravity. Pe: ρg QH (W) or Pe = γQH / 1000 (KW) ρ: Density of the liquid pumped by the pump (kg / m3) γ: Gravimetric pumped liquid of the liquid γ = ρg (N / s) Mass flow Qm = ρQ (t / h or kg / s)

Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.

While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
