    Intake Design

    The 300 mm is ok, however 8" gives 1.23 m/sec velocity which is aceptable. The water intake in a lake shall be type floating supported by a floating pontoon with a screen basket for the intake. This is to have the intake always under the surface level but far from the lake bottom where sediments...

    Septic System Design

    It is understanding that a residential septic system is for human's waste water. This case is for commercial application and shall be treated as is. Simple as you want go to Nadayic and for design manual click http://consolidatedtreatment.com/manuals/Nayadic_Design_Manual.pdf Nevertheless, Flows...

    Pumps TDH for slurry

    Thanks for your reply, Artisi. I continue a bit confused: The standard formula for water include the Sg of water which is 1, and the slurry pump also has Sg, in this case 1.5. The pressure generated by water is head times 1, and the pressure generated by slurry pump is head times Sg=1.5. So the...

    Pumps TDH for slurry

    I am designing a pump system for slurry which is a mixture of water, clay, and sand. The slurry has Specific gravity (Sg) 1.5. The manufacturer says that we don't have to calculate the Total Dinamic Head (TDH) affected by 1.5 due that the pump itself assume that difference: The head in meters of...

    Microstation old version?

    I just started in a new company found that they have an old version of Microstation (J). I asked why so knowing that new V8 version is more suitable. The Cad manager argument is that this new version has problems with PDS program in which most of the projects are running with. The question is...

    small stream water intake pipe

    Gerhardl is right telling most of the parameters you have to have in account for a general design. Roughly it is a good idea. However, you must have in consideration many others for having a good design: Topography, minimal deep of water in dry season, minimal flow, and quality of the water...

    Fire Suppression for Residual Fuel Oil burner

    I have designed fire protection with foam. It is regularly used for hydrocarbons and many other chemical products. Foam has to cover a fired surface (It does not work for 3 dimensions fire). It is a recommendation to use foam to combat fires on oil tank surfaces (on top of the tank). The foam...

    Grading Control Points

    The control points of the grading plan are the Bench Mark (BM) from the survey started surveying. Some times it is a relative altitude and some it is referred to the real altitude on earth. Other points of control the surveyor has to leave are more fix points that could not move along of the...

    corrosive water pipe

    This is a kind of situation in which I ask why having this corrosion problem dealing with forever trying to get a better quality of water? Why don't use other type of pipe material like SS, copper, or PVC (protected by steel pipe in case that expose to hard conditions that seems to be the concern)

    concrete grades please

    To make a correction about the concrete strength required typically in specifications and because we have still problems world wide with the imperial and SI units: 1 Newton (N)= 0.1019716 Kg force 1 Pascal = 0.1019716 Kg/m2= 1 N/m2 1 Megapascal = 101971.6 Kg/m2 = 0.1019716 kg/mm2 = 1 N/mm2 1...

    concrete grades please

    The grade 15, 25, 30 means the concrete compression resistance at 28 days. It is done in kg/cm2. Usually for most of the qualities of Portland Cement, sand, and gravel, the proportion is done in terms of volume: 1:2:3 for 1 cement sack volume:2 sand volume:3 gravel volume. This proportion...

    Fireflow model with sprinklers and hydrants

    According with NFPA 13, you must calculate the sprinkler system following the reasonable steps: 1. Choose the critical area (NFPA 13 establish the size of the area and the flow required according with the level risk), usually is the most remote area from the riser or from the feeding pipe i.e...

    Underground Domestic Water Testing

    You must follow the process of taking out the air into the pipe opening a relief valve at any upper point. If the loss of pressure persist and it is so difficult to found out the leaking, you have to account the water required to rise again the pressure. That is the convertion you are looking...

    Water Distribution Network Software

    I have used a program called Hidrocad for water calculation of hydrants and sprinklers. Also there is a nice program called Hidcal very useful due to the many options for simulation. This program is found in spanish.
