Question

A tank 4m long, 3m wide and 2m is filled to the brim with paraffin. (density 800kg /m3) calculate the pressure on the base.

Answer 1

pressure=weight/area
= 24m^3*800kg/m^3*9.8N/kg *1/12m^2
= 2*800*9.8 Pascals

Answer 2

Thanks alot it really helped me and I found this very helpful but can you do me a favour and please tell me how you had 9.8N/Kg

Answer 3

9.8N/Kg is the gravitational field strength of the Earth to two significant figures. Hope this helps!

Answer 4

why is the gravitational field strength sometimes 9.8 and sometimes 10?? like its different in some of my equations?
