A fluid flows through a 10-mm diameter tube at a Reynolds number of 1800. If the flow rate is 6.0 liters/min, what is the head l

Eddi Din [679]

Answer:

29.31 m

Explanation:

It is given that flow rate Q =6.0 ltrs/minute $=\frac{6}{1000\times 60}$ $m^3/sec$

Diameter =10 mm

So radius = $\frac{10}{2}=5 mm=5\times 10^{-3}m$

Area of duct $A=\pi r^2=3.14\times(5\times 10^{-3})^2=7.854 \times 10^{-5}m^2$

Average velocity $v=\frac{Q}{A}=\frac{10^{-4}}{7.854\times 10^{-5}}=1.372 m/sec$

The given Reynolds number is 1800 which is less than 2000 so it will be a laminar flow

So Reynolds number friction factor $f=\frac{64}{1800}=0.0356$

So head loss ifs given by $\frac{fLv_{avg}^2}{d\times 2\times g}=\frac{0.0356\times 100\times 1.732^2}{10\times 10^{-3}\times 2\times 9.81}=29.39\ m$

A hollow steel composite door with an 18-guage metal facing, hung on butt hinges with nonremovable pins, often with ventilation

Nadya [2.5K]

Answer:

Average industrial personnel door

Explanation:

Going by the description in which the door has ventilation louvers or glass panel, this shows that it can never be any type of security door. This is because with louvers or glass panel, it can be easier for any intruder to look or break into the house or space that is intended to be protected fully.

Hence, an hollow steel composite door with an 18-guage metal facing, hung on butt hinges with nonremovable pins, often with ventilation louvers or glass panels is likely an Average industrial personnel door
