So x is a variable which is just <span>character representing a number. We want to find x. To do this we want to get X by itself on one side of the equation. In this case/ we just need to divide both side by -4. Whatever you do to one side, you must do to the other. This gives us X = -12. To check yourself just plug your answer back into the equation to see if its right. -4(-12) = 48. You have successfully solved for X.</span>
Answer:
a) R(r) = kr⁴
b) R(r) = 1.5625 r⁴
c) R = 126.56 cm³/s when r = 3 cm
Step-by-step explanation:
Rate of flow of a gas through a cylindrical pipe = R
radius of the pipe = r
a) R ∝r⁴
R(r) = kr⁴ where k is the proportionality constant.
R(r) means R is a function of r.
b) R(r) = kr⁴
R = 400 cm³/s, r = 4 cm
400 = k × 4⁴
k = 400/4⁴ = 400/256 = 1.5625 (cm.s)⁻¹
R(r) = 1.5625 r⁴
c) R(r) = 1.5625 r⁴
R = ?
r = 3 cm
R = 1.5625 × 3⁴ = 126.5625 cm³/s = 126.56 cm³/s
