ENGINEERING HYDRAULICS c) An old railway line near Nsawam was drain by weed over-grown windingearth channel roughly 0.8m wide and with bank slope of about 1:16. The4channel is long and shallow, with a bed slope of about 0.1mm/m and only400mm deep at the lowest point. Engineers estimate the channel will needto convey a flow of about 0.23m/s in a five-year storm, to avoid creating adrainage problem when the lines reopen next year.

Engineering Standards and Codes

Standards are technical publications designed to ensure the reliability of goods, products, methods, or services. They establish technical requirements, specifications, guidelines, features, or design procedures. Standards recommend a set of tolerance for design, processes, operations, production methods, or equipments used in a particular area. Standards are not legally binding unless they are accepted as code or regulation.

How important is geology in structural engineering?
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. is traditionally broken into a number of sub-disciplines?? It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. ??? It takes 60 kW to keep the interior of a certain house at 60°C when the outside temperature is 10°C. This heat flow is usually obtained directly by burning gas or oil. Evaluate the power required if the 60 kW heat flow were supplied…
