Calculate the time taken to completely empty aswimming pool 15

user100 [1]

Answer:

Time needed to empty the pool is 401.35 seconds.

Explanation:

The exit velocity of the water from the orifice is obtained from the Torricelli's law as

$V_{exit}=\sqrt{2gh}$

where

'h' is the head under which the flow of water occurs

Thus the theoretical discharge through the orifice equals

$Q_{th}=A_{orifice}\times \sqrt{2gh}$

Now we know that

$C_{d}=\frac{Q_{act}}{Q_{th}}$

Thus using this relation we obtain

$Q_{act}=C_{d}\times A_{orifice}\times \sqrt{2gh}$

Now we know by definition of discharge

$Q_{act}=\frac{d}{dt}(volume)=\frac{d(lbh)}{dt}=Lb\cdot \frac{dh}{dt}$

Using the above relations we obtain

$Lb\times \frac{dh}{dt}=AC_{d}\times \sqrt{2gh}\\\\\frac{dh}{\sqrt{h}}=\frac{AC_{d}}{Lb}\times \sqrt{2g}dt\\\\\int_{1.5}^{0}\frac{dh}{\sqrt{h}}=\int_{0}^{t}\frac{0.62\times 0.3}{15\times 9}\times \sqrt{2\times 9.81}\cdot dt\\\\$

The limits are put that at time t = 0 height in pool = 1.5 m and at time 't' the height in pool = 0

Solving for 't' we get

$\sqrt{6}=6.103\times 10^{-3}\times t\\\\\therefore t=\frac{\sqrt{6}}{6.103\times 10^{3}}=401.35seconds.$

Mama L [17]

Answer:

C. Crankcase heater

Explanation:

The crankcase heater of the compressor was developed to mitigate the problematic variation of temperature on the in and out sides of the crankcase that has the capacity to change the physical states of the refrigerant and oil, cause them migrate and possibly mix together. It does so by allowing the regulation of the temperature on the inside of the crankcase
