66. In a paint mixing plant, two tanks supply fluids to a mixing cistern. The height, h, of the fluid in the cistern is dependent upon the difference between the input mass flow rate, q, and the output flow rate, qe. A nonlinear differential equation describing this depen- dency is given by (Schiop, 2010 dh A pA where A - cross-sectional area of the cistern, Ac - cross-sectional area of the exit pipe, g - acceleration due to gravity, and...
The answer is there but the method was confusing
7B.4 Flow between two tanks. Case 1: A fluid flows between two tanks A and B because Pa > PB. The tanks are at the same elevation and there is no pump in the line. The connecting line has a cross-sectional area S, and the mass rate of flow is w for a pressure drop of (PA -Ps(see Fig. 7B.4). Case I1: It is desired to replace the connecting line by...
just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
this pic is a note on constant surface temperature.
