Answer:
The correct option is;
(2) Boundaries are primarily used to indicate which functions a product will perform as opposed to the functions a user will perform
Explanation:
Product specifications accompanying most products, specifies the product boundaries and limitations which are to be acceptable to (or meet the requirement of) the intended user
The intended user has the option to then set boundaries of use of the product within his possession.
Answer:
Se necesita calentar un estanque de 400l de leche que empieza con una temperatura de 30 a 70 grados cuanto tiempo se tardará en llegar a esa temperatura? Destacar que en las conexiones pasa agua caliente a 70 grados y se transfiere el calorExplanation:
Answer:
diameter= 1 in
Explanation:
Some authors have developed studies to find the recommended flow rate at the pump outlet, in order to avoid high pressure losses and cavitation.
Assuming that this pump carries water, the recommended speed is 2m / s, so knowing the flow rate = 20gpm we can find the diameter of the pipe.
Q=flow rate=20gpm=0.0012618m^3/s
V=speed=2m/s
A=Area
Q=VA
A=Q/V

Taking into account that the flow is through a circular pipe we can use the equation to find the area of a circle, and then find the diameter
![A=\frac{\pi D^2 }{4} \\D=\sqrt[2]{\frac{4A}{\pi } } =\sqrt{\frac{4(630.8)}{\pi } } =23.34mm](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20D%5E2%20%7D%7B4%7D%20%5C%5CD%3D%5Csqrt%5B2%5D%7B%5Cfrac%7B4A%7D%7B%5Cpi%20%7D%20%7D%20%3D%5Csqrt%7B%5Cfrac%7B4%28630.8%29%7D%7B%5Cpi%20%7D%20%7D%20%3D23.34mm)
the result is 23.34mm, if we find the closest commercial diameter to this value, we find that it is 25.4mm = 1in
