Unable to calculate pressure drop in Preiodic Boundary condition in Fluent

So I took a simple problem of a 2cm x 2 cm x 5cm duct and gave a mass flow rate of 1kg/s with air as the fluid in order to simulate periodic BC over a total length of 50 cm. If I give the specified pressure drop and simulate the model I get the exact massflow rate but if I give the mass flow rate my pressure drop is giving bad numbers. What is the problem?

Do note that the pressure gradient is given as per m of length. And by bad, how bad do you mean?

By bad I mean almost zero pressure gradient. And yes iam talking about the pressure drop per length
