The density of a fluid is given by the empirical equation rho=70.5 exp(8.27 X 10^-7 P) where rho is density (lbm/ft^3) and P is

jasenka [17]

Answer:

(a) The unit of 70.5 is lbm/ft^3 and the unit of 8.27×10^-7 is in^2/lbf

(b) density = 0.1206g/cm^3

(c) rho = 0.1206exp(8.27×10^-7P)

Step-by-step explanation:

(a) The unit of 70.5 is the same as the unit of rho which is lbm/ft^3. The unit of 8.27×10^-7 is the inverse of the unit of P (lbf/in^2) because exp is found of a constant. Therefore, the unit of 8.27×10^-7 is in^2/lbf

(b) P = 9×10^6N/m^2

rho = 70.5exp(8.27×10^-7× 9×10^6) = 70.5exp7.443 = 70.5×1.71 = 120.6kg/m^3

rho = 120.6kg/m^3 × 1000g/1kg × 1m^3/10^6cm^3 = 0.1206g/cm^3

(c) Formula for rho (g/cm^3) as a function of P (N/m^2) is

rho = 0.1206exp(8.27×10^-7P) (the unit of 0.1206 is g/cm^3)

Answer:

gradient:

3x+2y=5

3(1)+2dy/dx=0

3+2dy/dx=0

2dy/dx=-3

dy/dx=-3/2.

y-intersect:

3x+2y=5

2y=5-3x

y=5-3x/2

NEED HELP FAST PLEASE

Hey!

To solve this equation, we'd first have to apply the distributing rule to this equation.

<em>Original Equation :</em>
$( 3a - 2 )^{2}$

<em>New Equation {Changed by Applying the Distribution Rule} :</em>
$( 3a )^{2} - 2$ · 3a · 2 + $2 ^{2}$

And now we simplify.

<em>Old Equation :</em>
$( 3a ) ^{2} -2$ · 3a · 2 + $2 ^{2}$

<em>New Equation {Old Equation Simplified} :</em>
$9a ^{2}$ - 12a + 4

<em>So, the equation $(3a - 2) ^{2}$ simplified is</em> $9a ^{2}$ - 12a + 4.

Hope this helps!
