Answer:
The pressure difference is <em>.</em>
Explanation:
To calculate the pressure difference, we use the fluid-kinetic equation:
<em>Δp = (8μLQ)/(πR⁴)</em>
Step 1: Convert the units of the given terms to SI units:
Diameter = 0.56 cm X ( =
∴ Radius, R =
Length, L = 22 cm X ( = 0.22 m
Volumetric flow rate, Q = ÷ 2.0 minutes =
X X =
Step 2: Input the terms into the fluid-kinetic equation:
<em>Δp = (8 X 0.60 X 0.22 X 3.67) / (3.142 X ()</em>
<em>Δp = 20067.43 Pa = .</em>
N.B: The pressure difference is lower than the atmospheric pressure (101300 Pa), which means you can drink the milkshake through the straw.
Explanation:
Mass = 40 g
edge of cube = 1.74 cm
volume of cube = s^3 = 1.74^3 = 1.74 * 1.74 * 1.74 = 5.268024cm cube
density = Mass/volume
= 40/5.268024
= 7.6 g/cm
It describes physics, chemistry and engineering. i dont know if you meant that but oh well.
