Volumetric flow rate

The paper reports water and gas flow measurements through carbon nanotubes with diameters of less than 2 nanometers. The measurement of water flow indicated that the values exceeded those predicted by hydrodynamics models by several orders of magnitude. The water flow rates were similar to those predicted from molecular dynamics (MD) simulations. The measurement of gas flow revealed that the predictions given by the Knudsen Diffusion model, commonly employed for systems in which the pore diameter

University of Oklahoma Department of Chemical, Biological and Materials Engineering Norman, OK 73019 Dr. Nollert, The experiment performed was Experiment IV: Fluid Flow Meters and Tray Hydraullics. The group was composed of Alex Long, Khanh Ho, Tricia Heitmann and myself. The first day of

first one was to start with target of the lab was to introduce a flat measure on the apparatus and research the energy produced by plane of water as it strikes the cup and second goal of the lab was to test and evidence the hypothesis of force stream rate by gathering information from trial and afterward handling this information to arrive at to the last conclusion. APPARATUS: • Gravimetric hydraulic bench • Impact of jet apparatus • Weights • Flat plate • Stop watch • Water supply

a test section, normal water loop, cold water loop, hot water loop and temperature measuring system. The water is used as working fluid. The test section and the connections of piping system are designed such that parts can be changed for different flow arrangement. The hot water loop consists of a storage tank, an electric heater of 3000W immerged inside the storage tank to obtain the high temperature of hot water, a pump and gate valve. The cold water loop consists of a storage tank, a pump and

Then the abrasive particles are passed into a connecting hose leading to the nozzle. This abrasive and gas mixture emerges from the orifice of nozzle at high velocity. The feed rate of abrasive air is controlled by the amplitude of vibration of the mixing chamber. A pressure regulator installed in the system controls the gas flow and

equation can be considered to be a statement of the conservation of energy principle appropriate for flowing fluids, it is possible to represent this principle using a simple formula in terms of the enthalpy of the fluid, assuming a steady, inviscid flow. h_t1-h_t2=Q_ht-W_sh Further assuming that there is no heat transfer (Q) into the fluid, as well as no work (W_sh) being produced, the equation simplifies to: h_t1=h_t2 Taking the definition of total enthalpy: E_2+P_2

has been a rapid increase in the use of the stirred tank bioreactors. The volumetric mass transfer coefficient (kLa) is often used to compare the efficiency of the bioreactors and as an important scale-up factor. It characterizes the oxygen mass transfer in stirred tank bioreactors. In the present work, a mathematical and statistical approach was adopted to study the effects of the various experimental variables on volumetric mass transfer coefficient in a 1 L stirred tank bioreactor. Air/water system
