Answer:
degree celsius
Explanation:
it's measured in degree Celsius
The flow will be laminar if Reynold's number
is less than 2000.
Use the Reynold's formula and rearrange to calculate velocity of water in the pipe.
Where, 
is velocity of the fluid, 
is the diameter of pipe, and 
is the kinematic viscosity i.e. 
for water at 288.7 K from Appendix.
So, velocity is:
The flow rate <em>Q</em>:
![Q = vA=v\pi D^2/4=\frac{\frac{N_R \nu}{D} \pi D^2}{4} =[tex] t = \frac{V}{\frac{N_R \nu \pi D}{4}} = \frac{4V}{N_R \nu \pi D} =\frac{4 \times 190 L\frac{10^{-3} m^3}{L}}{2000 \times 1.12\times 10^{-6} m^2/s \pi 15.24 cm\frac{1 m}{100 cm}} = 2226.3 s \frac{1 min}{60 s}= 37.1 min](https://tex.z-dn.net/?f=%20Q%20%3D%20vA%3Dv%5Cpi%20D%5E2%2F4%3D%5Cfrac%7B%5Cfrac%7BN_R%20%5Cnu%7D%7BD%7D%20%5Cpi%20D%5E2%7D%7B4%7D%20%3D%5Btex%5D%20t%20%3D%20%5Cfrac%7BV%7D%7B%5Cfrac%7BN_R%20%5Cnu%20%5Cpi%20D%7D%7B4%7D%7D%20%3D%20%5Cfrac%7B4V%7D%7BN_R%20%5Cnu%20%5Cpi%20D%7D%20%3D%5Cfrac%7B4%20%5Ctimes%20190%20L%5Cfrac%7B10%5E%7B-3%7D%20m%5E3%7D%7BL%7D%7D%7B2000%20%5Ctimes%201.12%5Ctimes%2010%5E%7B-6%7D%20m%5E2%2Fs%20%5Cpi%2015.24%20cm%5Cfrac%7B1%20m%7D%7B100%20cm%7D%7D%20%20%3D%202226.3%20s%20%5Cfrac%7B1%20min%7D%7B60%20s%7D%3D%2037.1%20min%20)

Where A is the area of cross section of pipe.
The time taken to fill is:
Where V is the capacity of the tank.
Convention is known as one of the driving forces of atmospheric circulation. Convection is defined as the heat transfer due to bulk movement of the molecules within fluids like liquids and gases, uncluding th molten rock. Convention takes place through diffusion, advection or can be both and it is usually a domination form of heat that transfer into liquids and gases.
The impact front the fall, depending on the distance, has an effect on the impact of their bones crushing with the pressure from the fall.
In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235.
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.
