- A batch drier removes water from a solid material at a rate of 30 lb/hr during the constant rate period. Under the operating conditions, the critical free moisture content is 0.5 lb H2O/lb dry solid, and the equilibrium moisture content is 0.04 lb water/ lb dry solid. The curve of drying rate versus moisturecontent may be assumed as a straight line during the entire falling rate period. Three hundred pounds of dry solid, containing 200 lb of water, enters the drier. How long will the total drying require if the final product contains 0.08 lb of water per lb of dry solid.A. 12.6 hr B. 1.27 hr C. 13.9 hr D. 19.3 hrpart 2. 1 kindly help me please need it BEFORE 9:10 pm i need the answer pleasee. THANK YOU SO MUCH! <3 -Derive the relationship between moisture content wet-basis and dry-basis3. Circular clarifiers are used to remove solid materials from water. They allow continuous treatment of water and can handle fairly large flows. Solids settle to the bottom of the clarifier and are carried away by a small stream of water (the waste stream). Most of the water exits the tank as treated effluent. Assume a clarifier receives a flow of 0.10 m3/s with a solid concentration of 800 mg/L. If the waste stream consists of 3% of the incoming flow and carries 90% of the incoming solids, a) what is the solids concentration in the waste stream, and b) what is the solids concentration in the treated effluent?
- Consider the following statementsProper use of internal vibrators include Vibrators can be used to move concrete horizontally To avoid the internal effects of bleeding, the vibrator should penetrate to the bottom of the layer and at least 150 mm into any previously placed layer The distance between insertions should be about 1 ½ times the effective radius of the vibrator To speed up the compaction, Internal vibrators can touch the reinforcing bars of the element but not the formwork. Of these statements Select one: A. All statements (1-4) are correct B. 2 and 3 are correct C. 2 and 4 are correct D. 1 and 3 are correcta) Mention the main characteristics of evaporation.b) Difference between particle specific surface and bed specific surfaceEffluent discharges from two secondary clarifiers were sampled.

The DO initial is measured to be 12.5 mg/L, and the DO final is measured to be 8.1mg/L.-A 10 mL sample volume of “B” secondary clarifier is placed into a BOD bottle with 290 mL ofdilution water. The DO initial is measured to be 14.5 mg/L, and the DO final is measured to be11.5 mg/L.a) Calculate the BOD5 concentrations for the secondary clarifier “A” and “B”, respectively.b) Which secondary clarifier discharge would be the greatest nitrification efficiency in the bodyof water in above question (3a)?

- Problem 4In water and wastewater treatment processes a filtration device may be used to remove water from the sludgeformed by a precipitation reaction. The initial concentration of sludge from a softening reaction is 20,000 mg/Land the volume of sludge is 100 m3. After filtration the sludge solids concentration is 350,000 mg/L. Assume thatthe sludge does not change density during filtration, and there is no accumulation of sludge in the filtrationdevice. Using the mass balance method, determine the volume of sludge after filtration.Please design a rapid sand filter that will effectively remove 65% of thesuspended solids in a flow of 10 cubic meters per minute. The suspendedmaterial consists of particles that are perfectly spherical with a diameter of 10microns. Please use sand with an effective size of 1 mm and a porosity of 0.5.You should limit your clean bed head loss to 0.5 meters per meter. (Pease use an attachment efficiency, α of 0.75)Viscosity of water =1.0087x10-3 Ns/m2Density of water =998.23 kg/m3What are the dimensions of this filter (Depth and Surface Area)?02: a)What precautions should we follow when conducting experiment in Environmental lab? b)How can you determine chloride content in a waste water sample?
