Throttling ValveWhich of the following statements about flow through an insulated throttling valve areaccurate? Answer ACCURATE or INACCURATE after each statement below. Velocities can beassumed to be small. Any reference to an "increase" should be interpreted as asking whetherthe quantity is greater on the downstream side of the valve.The enthalpy increases.downstream enthalpies are equal.a.and the upstream andb.Pressure increases sharply.and temperature increasessharply.C.There is negligible heat transfer with the surroundings.

1.a Injecting a gas (usually air or oxygen) at the bottom of a tank so that the turbulence caused by the rising gas bubbles serves to mix the liquid contents of the tank is called _________ mixing. b. The term ____________ encompasses the physical processes whereby the size of suspended particles increases as a result of particle cohesion following collisions brought about by the random thermal motion of fluid molecules and/or mixing of the bulk fluid containing the particles. c. Turbine and propeller type mechanical mixers used for rapid mixing of reagent chemicals have either -flow impellers with flat or curved blades located parallel to the axis of the drive shaft, or -flow impellers with blades making an angle of less than 90o with the drive shaft. d.Colloidal particles typically have a negative surface charge that attracts oppositely charged positive ions in the surrounding bulk solution. These so-called _______-ions are held at the particle surface through electrostatic and van…
As shown in the figure, air with a volumetric flow rate of 15,000 ft3/min enters an air-handling unit at 80°F, 1 atm. The air-handling unit delivers air at 45°F, 1 atm to a duct system with three branches consisting of two 26-in.-diameter ducts and one 50-in. duct. The velocity in each 26-in. duct is 16 ft/s.
