Report on chillers and fire fighting installtions
The document discusses cleaning and maintenance processes for chillers, air handling units, and ducts. It involves descaling condenser coils using hydrochloric acid to remove scale and rust. It also describes replacing a rusted chiller inlet pipe using oxyacetylene welding and cleaning fins in air handling units. Firefighting installations like butterfly valves and monitors are installed. Hoods are also cleaned by burning off accumulated oil. Load calculations for a chiller are provided using formulas for capacity based on mass flow rate, specific heat, and temperature difference.

This document summarizes an experiment on the high temperature deformation and creep behavior of polycrystalline magnesium oxide (MgO). MgO samples with different grain sizes were deformed under various stresses and temperatures. The results show that grain size is sensitive to dislocation creep, with smaller grain sizes resulting in higher strain rates. An analysis of strain rate versus stress, grain size, and temperature was conducted to determine the activation energy for creep based on the flow law for polycrystalline materials. The activation energy was found to be consistent with literature values for MgO.
