Different between Nm3/h = m3/h ? - OnlineConversion Forums

Re: Different between Nm3/h = m3/h ? The difference between Nm3/h and m3/h for compressor is very important because the first one correspond to standard conditions (1 bar and 20°C), where the density of the air is 1.2060 kg/m3. m3/h usually correspond to the flow at pressure conditions (7 bar and 60°C), where the density of the air is 8.3934 kg/m3.

Volume Calculator

Related Surface Area Calculator | Area Calculator. Volume is the quantification of the three-dimensional space a substance occupies. The SI unit for volume is the cubic meter, or m 3.By convention, the volume of a container is typically its capacity, and how much fluid it is able to hold, rather than the amount of space that the actual container displaces.

Pyramid Volume Calculator

Pyramid volume formula. A pyramid is a polyhedron formed by connecting a polygonal base and an apex. The basic formula for pyramid volume is the same as for a cone: volume = (1/3) * base_area * height, where height is the height from the base to the apex. That formula is working for any type of base polygon and oblique and right pyramids.
