The radius of a 10 inch right circular cylinder is measured to be 4 inches, but with a possible error of ±0.1 inch. What is the
lidiya [134]

Answer:

25.13274125 in³


Step-by-step explanation:

The radius = 4 ± 0.1

height = 10

Volume of a cylinder = πr²h

Actual volume of the cylinder = π × 4² × 10

                                                  = 502.6548246

Maximum volume = π × 4.1² × 10

                              = 528.1017251

Minimum volume = π × 3.9² × 10

                              = 477.8362426

Average error = (528.1017251 - 477.8362426)/2

                        = 50.2654825/2

                       = 25.13274125 in³

The units are inches cubed.

A flow meter is attached in a hydraulic line that measures 18 gal/min. The line has an inside diameter of 1.0 in. What is the fl
snow_tiger [21]

The flow velocity measured as in/min at the meter is 5924.13 in/min

<h3 /><h3>Volumetric flow rate</h3>

We know that the volume flow rate Q = Av where

  • A = cross-sectional area of pipe and
  • v = flow velocity

Now, Q = 18 gal/min

Converting this to in³/min, we have

Q = 18 gal/min = 18 × 1 gal/min = 18 × 231 in³/min = 4158 in³/min

A = πd²/4 where d = diameter of pipe = 1.0 in.

<h3 /><h3>Flow velocity, v</h3>

Since Q = Av, making v subject of the formula, we have

v = Q/A

v = 4Q/πd²

Substituting the values of the variables into the equation, we have

v = 4Q/πd²

v = 4 × 4158 in³/min ÷ π × (1.0 in)²

v = 16632 in/min ÷ π

v = 5924.13 in/min

So, the flow velocity measured as in/min at the meter is 5924.13 in/min
