What is nanoscience?

Nanoscience is the study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales where properties differ significantly from those at a larger scale.

Volume flow rate: The volume of fluid passing by a given point per unit time throughan area is called the volume flow rate, or simply flow rate. Q Q= dv/dt Consider an ideal fluid flowing with velocity through a uniform flow tube of cross section A. If, as shown in Fig. 2.34, the shaded cylinder of fluid of length x and volume V flows past point P in time t The 51 unit for volume flow rate is the cubic metre per second (m/s) Another common unit accepted in SI is the litre per minute (L/min).An old non-Sl unit from FPS system still used is the cubic feetper second (symbol, cusec). Mass flow rate : The mass of fluid passing by a given point per unit time through an area is called the mass flow rate dm/dt. Consider an ideal fluid of density p flowing with velocity o through a uniform flow tube of cross section A. If, as shown in Fig. 2.34, the shaded cylinder of fluid of length x and volume V flows past point P in time t Continuity condition for a flow ...
