Hello,

I have a problem. I want to make plot 3d for pressure drop in diffuser by posuille formula,

plot3d(∫_0^l▒〖(128∙1.2∙〖10〗^(-3)∙〖10〗^(-14))/(π∙〖(d+2∙x∙tan⁡〖θ)〗〗^4 ) dx,d=0.1∙〖10〗^(-6)..1.5∙〖10〗^(-6),l=5∙〖10〗^(-6)..50∙〖10〗^(-6),axes=box,font=[TIMES,ROMAN,13])〗

but with increasing of "l"(length of channel) graph shows wrong pressure drop. Normally with i increasing of "L" we should have...
