What is the physical significance of Fourier number? The Fourier Number (Fo) is a dimensionless group which arises naturally from the nondimensionalization of the conduction equation. It is very widely used in the description and prediction of the temperature response of materials undergoing transient conductive heating or cooling. What is the physical interpretation of the […]

What is Solar Pond?
What is Solar Pond? A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a “halocline”, in which low-salinity water floats on top of high-salinity water. What is Solar Pond explain with diagram? A solar pond is a solar […]

What causes high BOD in wastewater effluent?
What causes high BOD in wastewater effluent? Hydrolysis converts particulate organic matter to soluble and easily degradable organic acids which is why you measure an increase in BOD. What is the limit of BOD on discharge of wastewater on the surface water? 350 mg/L In which way sewage can be treated? Four common ways to […]
What is the most effective method to protect against a fall hazard?
What is the most effective method to protect against a fall hazard? include use of stairs, guardrails, and barriers to prevent the employee from direct and unprotected exposure to the fall hazard. These techniques prevent the fall before the onset. Control of falls is the last line of defense. How can hazards be prevented from […]
Why butane has a higher boiling point than 2 Methylpropane?
Why butane has a higher boiling point than 2 Methylpropane? Butane has a higher boiling point because the dispersion forces are greater. The molecules are longer (and so set up bigger temporary dipoles) and can lie closer together than the shorter, fatter 2-methylpropane molecules. Why do intermolecular forces increase with size? The strength of London […]
