  2. Enthalpy–entropy chart - Wikipedia

    en.wikipedia.org/wiki/Enthalpy–entropy_chart

    A horizontal line in the diagram represents an isenthalpic process. A vertical line in the h–s chart represents an isentropic process. The process 3–4 in a Rankine cycle is isentropic when the steam turbine is said to be an ideal one. So the expansion process in a turbine can be easily calculated using the h–s chart when the process is ...

  3. Strapping - Wikipedia

    en.wikipedia.org/wiki/Strapping

    Well set up strapping machines or friction weld tools will aim for around 80% of break strength. Metal clips/seals [vague] are surprisingly low [editorializing] with about 100 – 120 kg slip resistance. For pallets strapping based on norm ASTM D3953 Standard Specification, the number of the strapping procedure is around 10 times for a minimal.

  5. Heisler chart - Wikipedia

    en.wikipedia.org/wiki/Heisler_Chart

    These first Heisler–Gröber charts were based upon the first term of the exact Fourier series solution for an infinite plane wall: (,) = = [⁡ + ⁡ ⁡], [1]where T i is the initial uniform temperature of the slab, T ∞ is the constant environmental temperature imposed at the boundary, x is the location in the plane wall, λ is the root of λ * tan λ = Bi, and α is thermal diffusivity.

  6. Moody chart - Wikipedia

    en.wikipedia.org/wiki/Moody_chart

    In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.

  8. Fibre-reinforced plastic tanks and vessels - Wikipedia

    en.wikipedia.org/wiki/Fibre-reinforced_plastic...

    Tanks listed as suitable for outdoor service are protected from UV attack by: coloring or pigmenting and/or adding internal stabilizers which preferentially absorb or dissipate the UV energy. Shading tanks from the sun will also prevent deterioration. Tanks must be free to expand or contract, avoid excessive tension on the tank.
