The question wanted it in terms of the constants, the topic I'm doing involves partial differentiation it seems weird that there is no partial differentiation
hi
How can I differentiate this?! Is it just
(Terms)^1/2 and differentiate using chain rule?
Also how would I be able to get rid of the t's at the end?
Homework Statement
The problem and my attempt are attached
Homework Equations
Chain rule for partial differentiation perhaps
And basic algebra
The Attempt at a Solution
I'm unsure of how to approach this but I differentiated all the expression at the top.
Thanks Chet, I also realized that Reynolds number will not be the same due to a variation in the drag constant. So we cannot use the same Reynolds number as the first part
I completed 4a successfully, and with 4b, i have 2 queries:
a)why can't I let Reynolds # equal to 2.19 x 10^5 (from part a) then simply sub v=4 instead of 5m/s and rearrange for viscosity? I tried it this way first and got a very wrong answer. Why do we, essentially, need to work backwards to...
see I worked through 3a) and I was comparing answers, I saw that they omitted v2 (5m/s) their explanation was because it was "defined in the question" I'm not sure what that means 3)b I tried understanding what's going on but I am clueless unfortunately, how exactly did they get 12.1m ? Where is...
Thank you for all the answers,For q4
-mfb states that there can only be one direction for constant pressure, could you please elaborate?
For q5
- velocity must be constant because Qin=Qout BUT if you look at the pressure in p1 and p2 you shall see that pressure is different.. Now using...

Pics are attached, my concerns are with question 4 and 5.
For q4
-which way is flow? How do we know?
-the working then goes on to say that energy loss is compensated by increasing...
