P14.003A spherical gas-storage tank with an inside diameter of 8.1 m is being constructed to store gas under an internal pressur
Artist 52 [7]

Answer:

The minimum wall thickness required for the spherical tank is 0.0189 m

Explanation:

Given data:

d = inside diameter = 8.1 m

P = internal pressure = 1.26 MPa

σ = 270 MPa

factor of safety = 2

Question: Determine the minimum wall thickness required for the spherical tank, tmin = ?

The allow factor of safety:

\sigma _{a}  =\frac{\sigma }{factor-of-safety} =\frac{270}{2} =135MPa

The minimun wall thickness:

t=\frac{Pd}{4\sigma _{a} } =\frac{1.26*8.1}{4*135} =0.0189m

The piece of wood shown above has a mass of 20 grams. Calculate its volume and density. Then
kozerog [31]

We have that The Density and Volume is given as

\rho=0.67\\\\\V=30cm^3

The factors that affect Density are Mass and Volume

From the question we are told that

The piece of wood shown above has a mass of 20 grams.

Wood parameters

2cm

5cm

3cm

Generally the equation for the Volume  is mathematically given as

V=L*B*H\\\\\V=2*5*3\\\\V=30cm^3

Generally the equation for the Density is mathematically given as

\rho=\frac{m}{v}\\\\\\rho=\frac{20}{30}\\\\\rho=0.67

Therefore the factors that affect Density are Mass and Volume
