The phrase "a power of about" is correct and usable in written English.
It can be used when discussing an approximate value of a quantity, often in scientific or mathematical contexts.
Example: "The device operates at a power of about 100 watts."
Alternatives: "an approximate power of" or "a power level of around".
The study sample should be large enough to reach a power of about 0.80.
The WSS consumed a power of about 16.9 mW at the supply power of 5 V.
The ITER project requires at least two Neutral Beam Injectors (NBIs), each accelerating to 1 MV a 40A beam of negative deuterium ions, to deliver to the plasma a power of about 33 MW for one hour as additional heating.
For a cell with the hybrid film (molar ratio P/Si = 1.5) as an electrolyte under H2 and air at 130 °C, 17% RH, the open circuit voltage of the cell was about 0.88 V and a power of about 50 mW cm−2 was obtained with current density of 150 mA cm−2.
It is shown that the generalization of the actuator disk theory is, at most, only valid for rigid wings, and for flexible wings, the power P varies by a power of about 1.0 of the thrust T. This aerodynamic information can also be used as benchmark data for unsteady flow solvers.
Studies will be led to detect suitable sites to realize the other projects during the period of 2016 to 2030 for a power of about 1,700 MW.
A 40 m wing span kite was expected to achieve a rated power of about 4.1 MW with a power density of about 52 kW/m2.
The accuracy of prediction using one of the available simple scoring systems [ 3, 4] is at best increased to a discriminating power of about 70% compared to a random guess with a pre-hoc accuracy of 50% [ 5, 6].
The cell showed an open circuit voltage of 1.80 V, a short-circuit cd of about 1.1 andm2 and a maximum power of about 0.5 W/cm2.
Thus, for example, a lens with a least distance of distinct vision of 25 cm and a focal length of 5 cm (2 inches) will have a magnifying power of about 5×.
"But we still manage to find quiet places, or at least moments in those quiet places, to listen". The transmitter on the lander has a broadcast power of about 14 watts, says Callas.
