Discuss five technologies applied in water resources development and Environmental Management.

A light cable with negligible weight is suspended between two points spaced 480 m apart

horizontally with the right support 42 m higher than the left. Five vertical gravity

loads of 753, 2899, 5322, 1780 and 2130 kN (from left to right) centered

between the supports and spaced 80 m apart horizontally are applied to the cable. If the

largest sag is 56 m, calculate

a cutting diagram shows how parts should be arranged so they can be produced with the minimum number of cuts?

A 50 m steel tape was used to lay out a 500 m race track. During taping, the temperature was 32 deg C and the pull applied throughout was 8 kg. If the tape is of standard length at 15 deg C and a pull of 6 kg, what should be the correct length to layout considering corrections for temperature and pull?

Initially a tank holds 100 gal of a brine solution containing 4 lb of salt. At t = 0, brine containing 3 lbs of salt per gal is poured into the tank at the rate of 4 gal/min, while the wellstirred mixture leaves the tank at the rate of 4 gal/min. How long will it take for the tank to contain 10 lb of salt?

In 8:00 am, the population of a bacteria is 1000, At 11:30 am, the number of bacteria triples. What will be the population at 8:30pm?

A vertical face ogee 1.5m is operating at a design head of 3m. Calculate the depth of flow immediately dowmstream from the weir

The planimeter is a mechanical device used for determining the area of many shape of figure plotted to unknown scale. It's design is based on the principle that the amount the roller turns is a measure of the area

Simpson's One Third Rule is based on the assumption that the curved boundary consists of parabolic arcs, where each arc is continuous over three adjacent offsets that are equally spaced. Because of this assumption the rule is only applicable when there is

The assumption made in using the Trapezoidal Rule is that the ends of the offsets in the boundary line are assumed to be connected by
