where: H is the total power density emitted from the light source in W m-2; F(λ) is the spectral irradiance in units of Wm-2 μm-1; anddλ is the wavelength.. However, a closed form equation for the spectral irradiance for a light source often does not exist. Instead the measured spectral irradiance must be multiplied by a wavelength range over which it was measured, and then calculated over
Jan 28, 2020· The On Mode power consumption limits for large monitors are based on viewable screen area alone. In general, larger, high resolution monitors will have higher maximum on mode power consumption allowances than smaller, low resolution monitors. On average, monitors that have earned the ENERGY STAR are 7% more energy efficient than standard options.

May 01, 2012· High-throughput screening (HTS) is an efficient experimental approach to screen displacers from a number of existing compounds. In the screening, a known amount of adsorbent is equilibrated with a protein solution, and the amount of protein adsorbed is calculated by the equilibrium concentration in the supernatant.

How much electricity do computers use? A typical desktop computer uses about 65 to 250 watts. To find the figure for your particular computer you can contact the manufacturer (not me), or see my section on measuring electrical use.. Add another 20-40 watts for an LCD monitor, or about 80 watts if you have an old-school 17" CRT.
Feb 25, 2015· Crushing efficiency has been defined in the literature from the power consumption point of view. But while operating a process plant, it is more important that the crushing efficiency is defined in terms of the requirement of subsequent process. The Process plant has been designed for coal size - 13 mm ( 80 % passing).
The following information is required to calculate the two screen efficiencies;- Qms (f) = Mass flow rate of solid feed. Qms (o) = Mass flow rate of solid in the screen overflow. Qms (u) = Mass flow rate of solid in the screen underflow.
By using Figure 13, the efficiency factor for any other screening efficiency can be obtained. For example, for a screen with 90% efficiency the factor is 1.0, and for a screen with 70% efficiency the factor is 1.2. The efficiency factor can also be used as a fudge factor for making calculated results agree with measured results.
Where, P100 is the closing screen aperture (µm), Gpb is the net screen undersize product per revolution in the labora-tory ball mill (g), P80 is 80% passing size of the product (µm), F80 is 80% passing size of the circuit feed (µm), f(P80) is P80 F80
