Hi!I was wondering if someone can point me in the right direction.Suppose you have a cylinder with a center drilled hole, at the end of the hole a perpendicular hole is drilled through the cylinder wall as shown below: How can i calculate the pressure drop if the fluid flows from left to right.   The fluid is turbulent   Regards Sigurd

Hello Everyone. From : Plotting a local minimum-point of g(x) ? Thanks in advance. Regards.

Greetings, i am trying so solve the attachted differentialsystem in Mathcad 15. Note, that im not THAT familiar with the program.The last few days i spent searching this forum, but i couldnt get any clue. The error massage seems to vary within an Hour    Some Background: This is a differentialsystem, which describes the motion of an impacted panel and the impactor.   Thanks in advance

To all   Dug out an old mcad sheet and was hoping to had a "check" but I am having a problem in properly defining either a Find or use the solve option. It's very embarrassing    Can someone advise the mistake I made in setting either option? see attached mcad 15 sheet   Thanks Regards    

When I have 20 elements in vectors with operators (for parallel calculation of 4 curves) all is OK! When I have 40 elements in vectors with operators (for parallel calculation of 8 curves) it is not OK! See please attach! My Mathcad Prime 4 is break when I open the converted 8-Flyers file! Help please  

I have an error in my solve block that is solving for my forces as a function of time. The error is all the way at the bottom of the code. I am not sure how to resolve the error. Can someone help me?

I am having some issues with a solve block. I have had this issue before, but I forgot what I did to fix it. I get an error message that says "No solution was found. Try changing the guess value of TOL or CTOL." Can someone help me? The issue is at the bottom of the code.

Hello Everyone. From: https://www.wolframalpha.com/input/?i=solve+e%5E(x)-1%2F(e%5E(x*i))%5Ei)%3D0 The question : How many solutions does the g(x) could have ? Thanks in advance. Regards. Loi.

Hello,   Please help to solving two tasks with MathCad? 1) Water tank, the base of which runs through the water, is filled with 50 cm heights. It is known that the leakage rate is proportional to the square root of the water column. During hour, the water level dropped 9 cm. How long is the water level dropped to 40 cm and when the tank is empty? 2)During the test, the stone was placed at a temperature of 60 ° in the current form at 20 degrees in water. The stone was cooled to 40 ° C for 2 minutes. Find the temperature of the stone for 5 and 10 minutes after. Graphs is needed Please feedback Br.V

H From the above. The question is the "red", the above.  "-23.561944901920921149 or 1.835265713166714" A confusing ? Or both are true ? Regards. Loi.

Hello Evryone. From : Finding another solution from the symbolics' hint ? Thanks in advance.

Hello to all!Tonight I am working on what should be a simple problem as below:I know that from my reading material I have been given that:So for my simple triangle problem I have started by defining y (assuming that y is symmetric about x as:I have then integrated using the given forumula for JT but I am not coming up with the model answer of 1/48*B^3*H I am instead getting H to the power of 4? Which is a reoccurring problem...Following the question I have used the same approach for JoL and JL given that these are defined as:NB JL is the only answer I get spot on but only by using the given answer for JoL not the one I have calculated.Further if anyone can elaborate as to how J1L would be derived for a base of x=H? The given answer seems to be the answer for JoL for a rectangular shape?As always your help is greatly appreciated.Andy

Hey guys,   Now i'm trying to model the concentration in respect of time and space and that's why i'm using PDE solver. However why it does not work and it gave en error that "it found singularity while evaluating the expression. Help please :(((

Hey guys,   I'm new in Mathcad and i have some derivatives that i already solved with ODE solver. However, i try to solve the equation by hand and i want to try simulate this integration to compare if the results is same or no compared to the one that ODE solver gave. But i don't know how to find the solver for integration, can you help me?   I attached my document. Thanks in advance

  Hello Everyone. From : solve , x , fully ?      Thanks in advance.             Regards.  

Hi guys! I am a totally beginner in MathCAD and trying to solve a system of two equations.   On one hand I have volume as a function of Pressure (V=f(Ps)) and other known parameters. Then I have two equations of compressor Head, one as a function of Ps (and other known parameters) and the other as a function of Volume again. So I could equal both equations of Head and have one equation with two variables V and Ps.   The thing is I can't find how to find Ps and/or V to satisfy the equations... Many thanks.

is it possible that explicit shows only numbers and short numbers like 2-3 digits

Hallo,   a repating question about Prime 5.   Has the all new Mathcad now ALL Features of the loving Mathcad 15?   Then i will test it in my company to suggest it.   The new optic and the possibility to make a text area with WORD functionality looks good to me.   lg Stefan
