Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research implied that liquids can only be transported in fixed direction on species with ...

From an engineering perspective, a water tube boiler is defined by the fact that water or steam–water mixture flows inside ...

The capillary tube — the simplest of refrigerant controls — is the most popular method for metering refrigerant flow from the condenser to the evaporator in compression-type refrigeration systems.

Effective water management involves supplying water according to the real requirement, and thus measuring water is very essential step in water management systems. There are many water flow ...
