Best ResponseYou've already chosen the best response.0how do you write this as function? \[X(t)=10+\delta(t)+\delta(t1)\]

Best ResponseYou've already chosen the best response.0Im not sure. I'll show you the question

Best ResponseYou've already chosen the best response.0i don't think its saying that the 1ft^3 of water still happen from t=0min to t=1 mins, otherwise it would be a step function (not an impulse function). Im not entirely sure

Best ResponseYou've already chosen the best response.0because in the end, after the last impulse, you want the inlet to be running at 10ft^3 of water (Since that is its steady state value; the impulses come from disturbances)

Best ResponseYou've already chosen the best response.1an impulse has infinite height right

anonymous

Best ResponseYou've already chosen the best response.0yes, but i guess we say that an impulse of 2 is greater than an impulse of 1, hypothetically speaking, despite both having infinite height

Best ResponseYou've already chosen the best response.0so you think my function is reasonable?

Best ResponseYou've already chosen the best response.1since 10 is not really a response

dan815

Best ResponseYou've already chosen the best response.1but i dont really know, it seems like its based on convention

Best ResponseYou've already chosen the best response.0dw:1444124866547:dw shouldnt it be like this?? the impulse is the derivative of this graph

dan815

Best ResponseYou've already chosen the best response.1then ur function would be X(t) = 10 + integral (unit impulse) + integral 2*unitimpulse

Best ResponseYou've already chosen the best response.1but they're saying sketch "response" of level vs time

anonymous

Best ResponseYou've already chosen the best response.0that is a function of step functions, we can't assume that the disturbance continues after t=0 to t=1

Best ResponseYou've already chosen the best response.1not level vs time right...

anonymous

Best ResponseYou've already chosen the best response.0i have the level v time sorted once i find the solution to the initial flow rate. i can just apply laplace and first order principles. but this is the important bit

Best ResponseYou've already chosen the best response.1the 10 isnt there anymoore in response thats initial condition

anonymous

Best ResponseYou've already chosen the best response.0so its just \[X(t)=\delta(t)+\delta(t1)\]

dan815

Best ResponseYou've already chosen the best response.1well shouldnt it be 2* impulse

dan815

Best ResponseYou've already chosen the best response.1also depedns on how u drew the level graph

Best ResponseYou've already chosen the best response.0i forgot to add that in all of my equations

Best ResponseYou've already chosen the best response.1u can also add an impulse of 10 at like t=inf or something

anonymous

Best ResponseYou've already chosen the best response.0dw:1444125308190:dw perhaps u can just scale it back by 1 and you have\[X(t)=10\delta(t)+11\delta(t1)\]

dan815

Best ResponseYou've already chosen the best response.1its still only 2 for the 2nd one

dan815

Best ResponseYou've already chosen the best response.1and 11 for hte first one

Best ResponseYou've already chosen the best response.1i take it u wannna saw theres 10 in the tank and 1 added same time?

anonymous

Best ResponseYou've already chosen the best response.0im not following, why is it 2, when we are inputting an impulse of a factor of 1 greater than the first impulse?

Best ResponseYou've already chosen the best response.0idont know why we need laplace transform and stuff since it jst ask to draw the level of the tank .. and from my graph we can easily find the levels at t=.5, 1, 1.5

Best ResponseYou've already chosen the best response.0@BAdhi we are continually removing water from the system

Best ResponseYou've already chosen the best response.1just show me your step function lo... itll be so much less confusing

anonymous

Best ResponseYou've already chosen the best response.0so the height will change after the impulse

dan815

Best ResponseYou've already chosen the best response.1just do it depending on ur step function

anonymous

Best ResponseYou've already chosen the best response.0but there is no step function...

Best ResponseYou've already chosen the best response.1i thought u drew that already

anonymous

Best ResponseYou've already chosen the best response.0well its kinds ambiguous to me cause you aren't adding water from the first disturbance from t=0 to t=1, only instantaneously..

anonymous

Best ResponseYou've already chosen the best response.0like all it is, is just a spike to the inflow, and thats it. it isn't flowing 11ft^3 of water from t=0 to t=1. only at an instantaneous period

Best ResponseYou've already chosen the best response.0any thoughts? i just need to find the function of inflow and i will be set. i just need to find what Q(t)=??

anonymous

Best ResponseYou've already chosen the best response.0Q(t) being the inlet flow into the tank

Best ResponseYou've already chosen the best response.1again that 10 cannot be there

dan815

Best ResponseYou've already chosen the best response.1having a continuous 10 means ur level was rising constant at a rate of 10 m^3 over some time increment

anonymous

Best ResponseYou've already chosen the best response.0then i don't know what to do.

anonymous

Best ResponseYou've already chosen the best response.0because, we aren't really adding step functions, because it would have told us that from t=0 to t=1, 1ft^3 is being added to the tank, (that is a step function) but here it doesn't say.

anonymous

Best ResponseYou've already chosen the best response.0so this would be an instantaneous disturbance
