The floor of a classroom is to be supported by the truss shown . Each truss is 5 m long and they are spaced 75 cm on centers (distance between 2 trusses). The floor itself is to be made from lightweight concrete that is 10 cm thick. Neglect the weight of the joists and the corrugated metal deck, and determine the load that acts along each truss. ( The total floor load Dead load + Live load).

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
