Pressure inside an air mattress!

  1. Apr 22, 2015 #1
    Hey guys,

    I am to design an air mattress to lift a patient of about 200kg.
    The dimensions of the mattress is 1000mm x 610mm x 250mm.
    The max flow rate from blower is 700lpm.

    What and how should i calculate the pressure with which i need to fill the mattress?
    Also, how to calculate the time required to fill for different patient weights?

    Thanks

    Is this homework? Please use the homework template.

    Do you know the definition & units of pressure? You have a mass and can estimate an area so can solve for pressure.

    You cannot find fill time without more blower specs.
