A100-mm pipe is used to transfer oil from a reservoir to a 100- liter tank. it takes 45 minutes to fill the tank with oil that has viscosity and density of 0.005 pas and 900 kg/m3, respectively determine a. the volume flow rate of oil b. mean velocity in the pipe; c. reynolds number, and d. the maximum velocity in the pipe

Explanation:

Given that,

Diameter =100 mm

Volume = 100 liter

Time = 45 min

Viscosity = 0.005 Pas

Density = 900 kg/m³

(a). We need to calculate the volume flow rate of oil

Using formula of flow rate

Put the value into the formula

The volume flow rate of oil is

(b). We need to calculate the mean velocity in the pipe

Using formula of mean velocity

Put the value into the formula

The mean velocity in the pipe is .

(c). We need to calculate the Reynolds number

Using formula of the Reynolds number

Put the value in to the formula

The Reynolds number is 84.6.

(d). We need to calculate the maximum velocity in the pipe

Using formula of maximum velocity

Put the value into the formula

The maximum velocity in the pipe is

Hence, This is the required solution

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
