Answer:
a. 0.5x10⁵
Explanation:
The charge density = 10C/cm²
We are asked to find the magnitude of the electric flux density
The electric field of infinite sheet
E = σ/2Eo
We have electric density as follows:
D = EEo = EoE
Since charge density σ = 10C/cm²
σ = 10x10²C/m²
D = σ/2
10x10⁴/2
= 5x10⁴C/m²
= 0.5x10⁵C/m²
Therefore the magnitude is equal to 0.5x10⁵C/m². Which gives us option a as the answer
Answer:
use the dimensions shown in the figure
Answer:
Space velocity = 30 hr⁻¹
Explanation:
Space velocity for reactors express how much reactor volume of feed or reactants can be treated per unit time. For example, a space velocity of 3 hr⁻¹ means the reactor can process 3 times its volume per hour.
It is given mathematically as
Space velocity = (volumetric flow rate of the reactants)/(the reactor volume)
Volumetric flowrate of the reeactants
= (molar flow rate)/(concentration)
Molar flowrate of the reactants = 300 millimol/hr
Concentration of the reactants = 100 millimol/liter
Volumetric flowrate of the reactants = (300/100) = 3 liters/hr
Reactor volume = 0.1 liter
Space velocity = (3/0.1) = 30 /hr = 30 hr⁻¹
Hope this Helps!!!
