A rapid-mixing basin is to be designed for a water coagulation plant, and the design flow for the basin is 15,140 m3/d. The basin is to be square with a depth equal to 1.25 times the width. The velocity gradient is to be 900 s-1 (at 10°C), and the detention time is 30s. Determine: a. The basin dimensions. b. The input power required. c. The impeller speed if a vane-disc impeller with six flat blades is employed and the tank is baffled. The impeller is to be 50% of the basin width. (use viscosity (u) = 0.0013 N-s/m²)

Answer
two reservoirs are connected by a cast iron pipe (roughness of 0.025 mm) with 75 mm in diameter and 250 m in length. Determine the speed and flow when the difference in level between two reservoirs is 14m and a reservoir is pressurized at 2 bar relative and the destination is at 5 psig of vacuum. Consider the kinematic viscosity of 5x10-7m2 / s. The correct alternative with speed values (in m / s) and flow (in m3 / h) is: a. 3,6 and 64,2 b. 4,7 and 59,7 c. 3,6 and 56,9 d. 4,1 and 65,4
The discharge through a concrete pipe of 1 ft diameter and 3000 ft length is 1.0 cfs. What is the head loss (hr) if the water temperature is 60°F? Apply the Darcy- Weisbach equation
1) The horizontal flow toward drains causes an increase in the length of the flow lines, and consequently the hydraulic head losses increases because the higher velocity of the water flow near the drain. * O True False

Problem1: A new coagulation water treatment plant is proposed to treat 0.1145 m³/s at an average temperature of 19 °C. The tank is circular, and the required water depth is twice the diameter. Using the following design assumptions: detention time=10s; velocity gradient = 800 s¹; impeller type: radial flow turbine with 6 flat blades and assume B-H/3. Determine a) The tank dimensions b) The impeller diameter knowing that the available diameters are 0.45 and 0.6 m c) The required input power

(a) Water at temperature of 20 °C is pumped from a reservoir to a large open surface storage tank through a piping system with diameter of 10 cm as shown in Figure Q1. A pump with pump head rise ha = 32 – 1 × 10°Q²,Q = is m? installed in this system. Besides, the pipe's fitting components installed in this piping system such as tee and long radius 90° elbows are flanged type. The total pipe length for the entire piping system from reservoir to storage tank is 48 m while the pipe length from reservoir to pump suction side is 8 m. The friction factor of the pipe in this system is estimated to be 0.02. The elevation difference between the reservoir and storage tank are estimated to be 18 m.
