At time stamp 2:38 while calculating the Entrance length you have used 0.06 in multiplying , what does that signifies
I am unable to open transportProperties file from constant folder, as it is unable to locate. However, gedit opens blank text file. Please help.

What do we mean exactly mean by Zero Gradient?
I am getting the following error while executing the blockMesh command.FOAM FATAL ERROR: cannot find file "/home/prinux/OpenFOAM/prinux-8/run/pipe/0/p" From function virtual Foam::autoPtr<Foam::ISstream> Foam::fileOperations::uncollatedFileOperation::readStream(Foam::regIOobject&, const Foam::fileName&, const Foam::word&, bool) const in file global/fileOperations/uncollatedFileOperation/uncollatedFileOperation.C at line 538.

This is the Error that i am getting after running solver "solver". Solver crashes after some time.Courant Number mean: 32.084 max: 1334.68#0 Foam::error::printStack(Foam::Ostream&) at ??:?#1 Foam::sigFpe::sigHandler(int) at ??:?#2 ? in "/lib/x86_64-linux-gnu/libc.so.6"#3 Foam::symGaussSeidelSmoother::smooth(Foam::word const&, Foam::Field<double>&, Foam::lduMatrix const&, Foam::Field<double> const&, Foam::FieldField<Foam::Field, double> const&, Foam::UPtrList<Foam::lduInterfaceField const> const&, unsigned char, int) at ??:?#4 Foam::symGaussSeidelSmoother::smooth(Foam::Field<double>&, Foam::Field<double> const&, unsigned char, int) const at ??:?#5 Foam::smoothSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const at ??:?#6 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/icoFoam"#7 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/icoFoam"#8 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/icoFoam"#9 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/icoFoam"#10 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6"#11 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/icoFoam"
Can we use the same length we get from this formula for simulation?
Can we increase end time? Will that change our results?
I am facing an error below while running the simulation.

Can I keep purgeWrite value = 0? how will this affect the simulation results?
You say that OpenFOAM gives velocity as 0.05m/s and pressure as 2.8 Pa. From where did you get these values?
