Answer:
1) The power needed to process 50 ton/hr is 135.4 HP.
2) The void fraction of the bed is 0.37.
Explanation:
1) For this type of milling operations, we can estimate the power needed for an operation according to the work index (Ei), the passing size of the circuit feed (F80) and the passing size of the product (P80).
We assume the units of Ei are kWh/t.
The equation that relates this parameters and the power is (size of particles in μm):
The power needed to process 50 ton/hor is
2) The density of the packed bed can be expressed as
being f the fraction and ρ the density of every fraction. We know that the density of the void is 0 (ρv=0) and that fv=1-fs (the sum of the fractions ois equal to the total space).
Then we can rearrange
The void fraction of the bed is 0.37.
Answer:
Zn(OH)2 + 2CH3COOH -----> Zn(CH3COO)2 + 2H2O
Explanation:
Zn(OH)2 + 2CH3COOH -----> Zn(CH3COO)2 + 2H2O
All organisms share certain characteristics of life, for example, all living things are made of cells and they must reproduce to make the next generation. Without these characteristics, there is no life.

Answer:</h3>
2.83 g/cm³
<h3>
Explanation:</h3>
- Density of a substance is the ratio of mass of the substance to its volume.
Therefore;
- Density is given by dividing mass of a substance by its volume.
- It is measure in g/cubic centimeters or kg per cubic meters.
In this case;
Density of Al = 2830 Kg/m³
We are required to convert is to g/cm³
We use the relationship;
1 g/cm³ = 1000 kg/m³
Therefore;
= 2830 kg/m³ ÷ 1000 kg/m³
= 2.83 g/cm³
Hence, 2830 kg/m³ of Aluminium is equivalent to 2.83 g/cm³
Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the When you breathe in, you take in the oxygen your cells need for cellular respiration. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration
