A grit chamber is designed for a flow-through velocity of 0.30 m/s, a depth of 0.9 m, and a length of 10.5 m. If inorganic particles have a specific gravity of 2.65,
A suspended solids analysis is run on a sample. The tare mass of the crucible and filter is 55.3520 g. A sample of 260 mL is then filtered and the residue dried to constant mass at 103 degrees C.
E on roads extending east and west and S on roads extending north and south.Those roads traveling east and west are designated a number and the letter E.
The homogeneous gate shown consists of one quarter of a circular cylinder and is used to maintain a water depth of 4m. That is, when the water depth exceeds 4m, the gate opens slightly and lets the
A first order reaction is employed in a destruction kind of a certain kind of microorganism. ozone is used as the disinfectant and the reaction is found to be dC/dt=-kC. where C is the concentration
A mixture containing 45 wt% benzene and 55 wt% toluene is fed to a distillation column. An overhead stream of 95 wt% benzene is produced, and 8.0 % of the benzene fed to the column leaves in the bot
the level of water in a city water tower is 125ft. above the ground. The tank is kept with an air space which can be pressurized with compressed air. It is important to maintain a pressure at the bo
A 3 m long curved gate is located in the side of a reservoir containing water. Determine the magnitude of the horizontal and vertical components of the force of the water on the gate.
A marble on the end of a massless string is rotating about a hole at O on a flat(horizontal) frictionless table. The mass originally rotates with an angular velocity theta'=w0 and r is constant at r
A carpenter uses a hammer to strike a nail. Approximate the hammer's weight of 1.8lbs, as being concentrated at the head, and assume that at impact the head is traveling in the -j direction.
