Install an air line dryer.

Double seated ball valves will hold pressure from either end whereas single seated will only hold pressure rating from one end.

Gate-leaf of slide gate move vertical or horizontal by means of screw hoist on its frame to open or close the waterway thus regulate the flow and it can be used as a type of sluice gate but other type of gates are also used as sluice gate like flapgate, radial gate,needle gate,automatic gate,fixed wheel type vertical gate etc. Also same type of gates when installed on diffrent structures called by that structure's gate like crest gate, head regulator gate, cross regulator gate, escape gate, etc.

There is insufficient information to peform the calculation. The key information required would be the flow rate.

This is because the flow rate could be anything for a given pressure (say 80psi) therefore the pressure value alone is insufficient for determination.

For ductile materials, the yield stress is always lower than the tensile strength of the material. For brittle material they can usually be considered the same point. Steel is generally considered ductile.

The Schmid factor m is part of the equation for the critical resolved shear stress τ0.

The critical resolved shear stress is the component of shear stress in a slip plane, resolved in the direction of slip, necessary to initiate slip in a grain (plastic deformation in metals).

m = cos(κ)cos(λ) ; τ0 = mσ

κ - the angle between the applied load direction and the slip plane normal.

λ - the angle between the applied load direction and the slip direction.

σ - the applied stress or load

There are 6 vectors used to describe the strain field of an element. An equivalent strain is just a single numerical value used to represent the strain field.

Basically, a culvert means a covered hydraulic structure which conveys fluid. Therefore in a broad sense, pipe culverts in a small scale represent normal pipes like precast concrete pipes.

In terms of hydraulic performance, circular section is the best geometrical sections among all. Therefore, for relative small discharge, precast concrete pipes and ductile iron pipes are normally used which are circular in shape. But for applications of very large flow, precast concrete pipes and ductile iron pipes may not be available in current market. In this connection, cast-in-situ construction has to be employed. It is beyond doubt that the fabrication of formwork for circular shape is difficult when compared with normal box culvert structures. However, circular shape is the most hydraulic efficient structure which means for a given discharge, the area of flow is minimum. Therefore, it helps to save the cost of extra linings required for the choice of box culverts.

However, box culverts do possess some advantages. For example, they can cope with large flow situation where headroom is limited because the height of box culverts can be reduced while the size of pipe culverts is fixed. Secondly, for some difficult site conditions, e.g. excavation of structure in rock, for the same equivalent cross-sectional area, the width of box culverts can be designed to be smaller than that of pipe culverts and this enhances smaller amount of excavation and backfilling

P1 Material is the name given to Carbon Manganese Steel in the engineering industry

I believe drill-rod is harder than ordinary, cold-rolled steel - I cant give the specs to back that up definitively, but in my 14 yrs of industrial maintenance experience, I believe that to be correct.

I agree if I am right in thinking that "drill-rod" is the material called "silver-steel" in the UK. This is an alloy capable of being hardened and tempered to make cutting-tools, spindles etc, but is pretty tough to machine even in its annealed state. Cold-rolled mild-steel in turn, is tougher than hot-rolled m.s. but I don't know if it is any stronger. That would depend on the specific alloy rather than process.

A fire wall is what protects and controls the incoming and outgoing network traffic. A fire barrier blocks more of the things that can come in and go out of the network.

The first conveyor belt was invented by a man named Richard Sutcliffe in 1905. They used them in coal mines which caused a big transformation in the mining industry.

ac condenser means "Air Cooled Condenser". The cooling media is Air.

The fluid or anything which is being circulated through (inside) the coils /tube being cooled by the exposed or forced air - which impinges over the outside of the coil / tubes.

Think of a tensile load as a "pulling" force. A tensile load is the only type of load that can be taken by a rope, for instance.
