Power number is a dimensionless number used in fluid mechanics to characterize the ratio of inertial forces to viscous forces in a fluid flow.

• Power number is used to determine the efficiency of mixing in agitated tanks.

• It is calculated as the ratio of the power input to the fluid by the agitator to the product of the fluid density, impeller speed, and impeller diameter.

• A high power number indicates a more vigorous mixi...read more

Filtration rate is the rate at which a substance passes through a filter or membrane.

• Filtration rate is commonly used in industries such as water treatment, pharmaceuticals, and food processing.

• It is measured in units such as liters per hour or gallons per minute.

• Higher filtration rates indicate faster flow of substances through the filter.

• For example, a water filtration system may have a filtration rate of 10 liters p...read more

Distillation rate calculation involves determining the amount of material distilled over a certain period of time.

• Distillation rate is typically measured in units of mass or volume per unit time.

• It can be calculated by dividing the amount of material distilled by the time taken.

• For example, if 100 grams of a substance is distilled in 1 hour, the distillation rate would be 100 g/hr.

Heat exchanger design involves selecting the appropriate type, size, and materials to efficiently transfer heat between two fluids.

• Consider the type of heat exchanger needed (e.g. shell and tube, plate heat exchanger)

• Calculate the required heat transfer area based on heat load and temperature difference

• Select materials compatible with the fluids and operating conditions

• Optimize flow rates and configurations for maximum...read more

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

• Specific heat is a physical property of a substance.

• It is measured in J/kg°C or cal/g°C.

• Different substances have different specific heat values.

• Water has a high specific heat, which is why it is used to regulate temperature in living organisms.

• Metals generally have lower specific heat compared to w...read more

Effectively managing shift casuals involves clear communication, training, and fostering a positive work environment.

• Establish clear expectations: Clearly outline roles and responsibilities for shift casuals to avoid confusion.

• Provide training: Offer comprehensive training sessions to ensure casuals understand procedures and protocols.

• Encourage open communication: Create an environment where casuals feel comfortable as...read more
