The modulus of elasticity for a ceramic material having 6.0 vol% porosity is 303 GPa. (a) Calculate the modulus of elasticity (i

Phantasy [73]

Answer:

modulus of elasticity for the nonporous material is 340.74 GPa

Explanation:

given data

porosity = 303 GPa

modulus of elasticity = 6.0

solution

we get here modulus of elasticity for the nonporous material Eo that is

E = Eo (1 - 1.9P + 0.9P²) ...............1

put here value and we get Eo

303 = Eo ( 1 - 1.9(0.06) + 0.9(0.06)² )

solve it we get

Eo = 340.74 GPa

Given A = {1,2,42,57,99,538,677}, B = {1,5,6,7,{2,3} , and C ={1,{7}, {8,9}}, answer the following questions, use the proper not

professor190 [17]

Answer:

c < 7

Explanation:

The cardinal indicates the number or quantity of the elements of a set, be this finite or infinite quantity.

Given, A = {1, 2, 42, 57, 99, 538, 677}

B = {1, 5, 6, 7, {2, 3} }

C = {1, {7}, {8, 9} }

Let's say the cardinality of the subset is: c

Inequality that represents the cardinality of any proper subset of A is: c < 7

Hope this helps!

A reservoir manometer has vertical tubes of diameter D518 mm and d56 mm. The manometer liquid is Meriam red oil. Develop an alge

Nat2105 [25]

Answer:

Explanation:

Given that :

the diameter of the reservoir D = 18 mm

the diameter of the manometer d = 6 mm

For an equilibrium condition ; the pressure on both sides are said to be equal

∴

$\Delta \ P = \rho _{water} g \Delta h_{water} = \rho _{oil} g \Delta h_{oil}$

$\Delta \ P = \rho _{oil} g (x+L) ----- (1)$

According to conservation of volume:

$A*x = a*L$

$\dfrac{\pi}{4}D^2x = \dfrac{\pi}{4}d^2 L$

$x = ( \dfrac{d}{D})^2L$

Replacing x into (1) ; we have;

$\Delta \ P = \rho _{oil} g ( ( \dfrac{d}{D})^2L+L)$

$\Delta \ P = \rho _{oil} g \ L ( ( \dfrac{d}{D})^2+1)$

$L = \dfrac{\Delta \ P}{\rho _{oil} g \ ( ( \dfrac{d}{D})^2+1)}$

Thus; the liquid deflection is : $L = \dfrac{\Delta \ P}{\rho _{oil} g \ ( ( \dfrac{d}{D})^2+1)}$

when the applied pressure is equivalent to 25 mm of water (gage); the liquid deflection is:

$L = \dfrac{\Delta \ P}{\rho _{oil} g \ ( ( \dfrac{d}{D})^2+1)}$

$L = \dfrac{\rho_{water} \g \Delta \ h}{\rho _{water} SG_{oil}g \ ( ( \dfrac{d}{D})^2+1)}$

$L = \dfrac{\g \Delta \ h}{SG_{oil}g \ ( ( \dfrac{d}{D})^2+1)}$

$L = \dfrac{25}{0.827 ( ( \dfrac{6}{18})^2+1)}$

L = 27.21 mm
