Q- The wastewater having an organic concentration of 54 mg// is flowing at a steady rate of 0.8m³ /day through a detention tank of dimensions 2mx4mx 2m. If the contents of the tank are well mixed and the decay constant is 0.1 per day, the outlet concentration (in mg/l, up to one decimal place) is

Q: 10.13 m3/s and a BOD of its own equal to 5.5 mg/l. The deoxygenation constant, Kd, is…

A: given data:-  population P =350000 flow rate Q =1.93m3/s ultimate BOD of treated waste (LO)W =60Mg/l…

Q: If the BOD; for some wastewater is 220 mg/L and the ultimate BOD is 310 mg/L, find the reaction rate…

A: BOD5 = 220 mg/L BODt= 310 mg/L we know BODt = Lo (1-e-kt) 220 = 310 (1-e-5k) e-5k = 1-220310 -5k =…

Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.
