MPX5010DP Conversions

I am working on developing a pitot tube system for a school project. I am using an MPX5010DP sensor to measure the differential pressure between the static and dynamic ports. I have this connected to an Arduino to convert the outputted values of the sensor to velocity. I am struggling with converting the output to pressure values, does anyone have any knowledge on how to do this and set up the sensor? 

Thanks

Hello Charlotte, 
 
To convert the output voltage to pressure you can use the following transfer function shown in Fig. 4 of the datasheet:

Vout = Vs x (0.09 x P + 0.04) =>
P [kPa] = (Vout/Vs - 0.04) / 0.09
