What does MBH stand for and how is it used?

MBH stands for thousand British thermal units per hour and is a unit for expressing heat output rates, commonly in HVAC and heating equipment.

What is water horsepower used for?

Water horsepower quantifies the mechanical power required to move water against a head, commonly used in pump sizing and hydraulic power calculations.

Can I directly convert MBH to mechanical power?

Conversion assumes equivalency in context, but MBH measures heat, whereas mechanical power depends on flow conditions and fluid properties.
