An enrichment plant has a throughput of 32,000 kg U/day and produces 26,000 kg U as tails. What is the enrichment of the product

torisob [31]

Answer:

1.10 %

Explanation:

The enrichment of the product can be calculated using the following equation:

$\frac{W}{P} = \frac{x_{p} - x_{f}}{x_{f} - x_{w}}$ (1)

<em>where W: is waste or tails = 26000, P: is the product = 32000, xp: is the wt. fraction of ²³⁵U in product, xf: is the wt. fraction of ²³⁵U in feed = 0.72% and xw: is the wt. fraction of ²³⁵U in waste or tails = 0.25%. </em>

By solving equation (1) for xp, we can find the enrichment of the product:

$x_{p} = \frac {W}{P} \cdot (x_{f} - x_{w}) + x_{f}$

$x_{p} = \frac {26000}{32000} \cdot (0.72 - 0.25) + 0.72 = 1.10%$

Therefore, the enrichment of the product is 1.10 %.

I hope it helps you!

A Coca Cola can with diameter 62 mm and wall thickness 300 um has an internal pressure of 100 kPa. Calculate the principal stres

GarryVolchara [31]

Answer:

$\sigma _1=10.33MPa$

$\sigma _2=5.16MPa$

Explanation:

Given that

Diameter(d)=62 mm

Thickness(t)= 300 μm=0.3 mm

Internal pressure(P)=100 KPa

Actually there is no any shear stress so normal stress will become principle stress.This is the case of thin cylinder.The stress in thin cylinder are hoop stress and longitudinal stress .

The hoop stress

$\sigma _h=\dfrac{Pd}{2t}$
