H.W: An activated sludge process operates under the following data: Q=0.21 m³/s, S.- 250 mg/l, S-6.2 mg/l, MLVSS (X) = 3500 mg/1, 0= 10 days Return sludge concentration (X)= 10000 mg/l, Y=0.5, K₁ =0.06 d', volatile super solid represent 80% of SS, Find: 1- Treatment efficiency 2- Reactor volume 3- Qwa (sludge wasted from areation tank) 4- Qur (sludge wasted from recirculation tank) 5- Quantity of sludge wasted/day 6- Recirculated ratio V.X VX Qwa Qwr= Qwr-Xr 0X

For the beam shown, where should a uniformly distributed downward live load, wl, be placed to cause the maximum upward reaction at support A? (D, E, and F are the supports, from left to right, to the right of C.) B C a. From A to B and D to E b. From A to D and E to F c. From B to D and E to F ☑ d. From B to C and D to E L L

Question 1 1. A solid shaft of 1.55 m is used as a tractor propeller (prop) shaft. The shaft twists through 1.8 while rotating at 900 rpm. The diameter of the shaft is 60 mm and the modulus of rigidity is 85 GPa. Calculate 1.1 The maximum shear stress in the shaft 1.2 The power transmitted by the shaft. 2. The tractor has undergone minor modifications to increase the transmitted power by 20%. The solid shaft is replaced by a lighter hollow shaft of the same material, with a dimeter ratio of 2:1. Calculate the suitable dimeters of the hollow shaft.
