Transient Pressure Conditions

I'm modeling transient inlet pressure conditions on FLUENT for the first time. The function is rather easy:
P=10+2t ; where t=time (s)
But I need P to max out at 50Pa. I've read I can do this using User-Defined Functions on C language. Is this necessary?
If it is, I should just write the code and make sure to include #include "udf.h"
and UDF_PROFILE (inlet_pressure, passed-in variables)?
and how would I know what the correct names of the passed-in variables? Also, once the file is written, all i have to do is compile it using the DEFINE window when I start the calculation set-up?
Please advise me if I am wrong about anything. Thank you in advance for your help.

It's more straightforward to use transient profile:
(pressure transient 3 0)
(time 0 20 21)
(pressure 10 50 50)
