A 600 gallon brine tank is to be cleared by piping in pure water at 1 gal/min. , and allowing the well-stirred solution to flow out at the rate of 2 gal/min. If the tank initially contains 1500 pounds of salt, a) how much salt is left in the tank after 1 hour? b) after 9 hours and 59 min?
y=x^2+C1e^2x+C2e^3x
Thank you again
can u help me obtain the general equation of this
(( xcsc (y/x) - y ))dx + xdy = 0
I solved for the loads on a tripod leg that creates a 45 degree angle with the ground. The leg is 2x2" tube. The legs fold up and then swings into open position and stopped by R2. After solving for the loads I rotated the leg to the horizontal position. I solved for the X&Y components. This allowed me to use a beam program with the Y loads and reactions to determine the moment diagram and bending stress. I would then solve for the axial stresses using the X components. I could then combine the bending stress and axial stresses.
Find the diff equation of family of circles with center on the line y= -x and passing through the origin.
THANK YOU :)
How to eliminate arbitrary constants
y=C1e^x+C2e^2x+C3e^3x
thank you :)
