The results from a settling column test performed on a municipal sewage from a certain town were as presented below. The experiments were conducted on a sample of sewage which is sieved through a 1.2 mm mesh to remove gross solids that would block valves. 501 of the sample weighed 1.352 gm. After drying. Sampling Time (min.) 0 60 180 360 Experimental results for amount of SS remaining in the sample (mg/l) Sampling depth (cm) 100 230 150 118 90 200 230 150 143 115 300 230 159 147 134 400 230 157 152 145 The sewage treatment work incorporates two primary settlement tanks each of a diameter of 25 m.

A thermocouple was used to measure the temperature. Over the range of temperatures expected in the experiment, a linear regression analysis was performed for the temperature as a function of voltage. The best-fit equation was T = (-0.008563 + 220*V), where V is the thermocouple voltage. The voltage was fed into a 11-bit A/D converter with a voltage range of -8 V to 8 V. Determine the measurement resolution (in °C) due to the ADC? O 0.851 None O 3.113 1.710 0.393 4.960 1.144 O 3.797
Topic : Mixture Flow Problem A tank initially holds 100 gal of salt solution in which 50 Ib of salt has been dissolved. A pipe fills the tank with brine at the rate of 3 gpm, containing 2 lb of dissolved salt per gallon. Assuming that the mixture is kept uniform by stirring, a drain pipe draws out of the tank at 2pm. Find the amount of salt at the end of 30 minutes. Ans. 171.24 Ib

Determine the resistance in each scenario presented. Explain whether the resistance is linear or not, and if not describe the relation, finally, explain how it can be linearized about a specific condition. Be sure to state the units and demonstrate that they are correct using the appropriate pressure/flow relation. a) Laminar flow An aqueous solution of 50% glycerol / 50% water is flowing through a pipe with the following system parameters: System_Parameters = (L = 100.0 D= 0.2 u= 0.022 p= 1150.0 9m=7.0 g = 9.81) units : L ~ m; D~ m; µ ~ Pa · s; p~ kg: 4. ~ 8: Confirm that this is laminar flow and then calculate the resistance. b) Pump Resistance from Pump Curve Consider the following pump curve: [Feet) (Meters] 30어 Find the pump resistance if the pump is supporting 15 meters of discharge head pressure, at a flow rate of 300 L/minute. 80- 250 7어 100 PSI L/min Determine the pump resistance in Pa 20어 6어85 PST 50 SCFM 5어 75 PST Note that standard pump curves are oriented opposite to the…
