Think 5 ways in FLOOD DEFENSES which it impacts on your daily life.

In a wheat growing area, the cultivable land is 200 acres and wheat will be cultivated to all of the lands. The permissible interval between two irrigation peak period is 15 days and the depth of the irrigation required for that particular soil & argo-climatic region at peak period is 2.5 in. If the total head for pumping is 80 ft, pump efficiency is 85%, mortor efficiency is 80%, and the maximum allowable operating period of the pump is 16 hr/day. Determine (a) the required pump capacity (Q) for that command area (b) capacity of the mortor (hydraulic horespower) and (c) rated capacity of the motor.

Consider a pile group consisting of three piles arranged at the vertices of an equilateral triangle. The total load S is initially distributed evenly over the three piles (each pile carries initially S/3). S is assumed to follow the normal distribution with mean value S and coefficient of variation 30%. The capacity of each pile is also assumed to follow the normal distribution with mean value 25/3 and coefficient of variation 20%. When the first pile fails in this group, its entire load of S/3 is transferred to one of the two surviving piles (the other surviving pile gets no additional load). When the second pile fails, its entire load is transferred to the last surviving pile. Compute the probability of failure of this pile group.

As a part of traffic management measure, it is proposed to ban the heavy vehicle from a city street. It has been observed that the mean free speed is 60 km/hr. The percentage flow is 1200 veh/hr. per lane, the composition being: Private Cars: 80, Commercial vehicle: 09 and Buses: 11. The average occupancy of the vehicle is privale cars: persons per cars and Buses: 35 persons per bus. 2%, After the commercial vehicles are banned, it is expected that 15% new cars are in the street and attraction 10% of cars in the street. But the average space occupied for new and attractive cars 1.0 persons per car. The average space occupied by each types of vehicles when stationary in the jamming condition is: Private car: 6m, commercial vehicles: 10m and bus: 8m. Find: (i) The maximum capacity of the street before and after the imposition of the ban on heavy vehicles. (ii) The mean speed of traffic in km/hr. before and after the imposition of the ban on heavy vehicles.

Determine the exact simple interest of 5,000 pesos for the period from jan. 15 to Nove. 28,1992, if the rate of interest is 22%
