The ____________ costs can often be the determining factor in a successful project. Group of answer choices Overhead Material Labor Profit

Who is responsible for conducting special inspections and ensuring the work completed complies with design documents and referenced standards, why are specical inspections required?

You are viewing Attempt 1/Continue Work * Incorrect The 123-kg industrial door with mass center at G is being positioned for repair by insertion of the 8° wedge under corner B. Horizontal movement is prevented by the small ledge at corner A. If the coefficients of static friction at both the top and bottom wedge surfaces are 0.65, determine the force P required to lift the door at B. Assume a = 1.4 m, b = 1.2 m, a = 8° A Answer: P = 1144.28 N B

How can new sustainable materials change dead load calculations in future designs in earthquake-prone areas?

Given the truss with loading shown. Note that the roller connection at Joint D is in atrack so that it cannot move in the x-direction, but it can roll in the y-direction.Solve the truss with the virtual load you would use if you are going to solve for the verticaldeflection at Joint E using the method of virtual work.Note: Just solve the truss. You DO NOT need to find the vertical deflection at Joint E.

Question (1): (18 Marks) Gaza City has a total population of 650,000 inhabitant, where 75% of the population is connected to wastewater collection system. The water consumption per capita is 100 L/day. Currently, the collected flow treated partially by aerated lagoon system. The municipality intend to change the treatment system to a completely mixed activated sludge system to be used for organic matter removal only to fulfill the Palestinian standards for reuse (Soluble BOD 30 mg/l). The given data from the municipality laboratory and assumptions: ⚫ The influent soluble Biological Oxygen demand = 500 mg/l. Biomass yield (Y) = 0.5 mg VSS/mg BOD removed • Endogenous decay rate constant (Ka) = 0.05d¹ • • The concentration of biomass (X) = 3000 mg MLVSS The concentration of recycled biomass (X) = 10000 mg MLVSS/L Growth rate (d) 2.5 1.25 100 For the completely mixed activated sludge system find the following: a) The average flow to the treatment plant. b) The mean cell residence time. c)…

Question (3): (20 Marks) You have been assigned to design a secondary wastewater treatment component based on a tricking filter technique. The flow rate is 3500 m³/day, the raw wastewater has a BOD5 of 600 mg/l. This wastewater is primarily treated with an efficiency of 35%. • Assume suitable design criteria to obtain a BOD effluent of 15 mg/l. Design the secondary clarifier • Perform all the necessary cheeks on your design.
