The maximum annual flows of a river can be modeled by the Gumbel law. The average of flow rates calculated with 57 years of observations is 8 m3/s and the standard deviation is 2.4 m3/s. The region is flooded with damage when the flow exceeds 10 m3/s.
a) What is the return period of the 10 m3/s flow. b) What is the throughput for a 100 year return period. c) Determine the 95% confidence interval around the flow calculated in b).

Calculate the firewater demand in (m3/min) for a building having 25 floors including basement. Building is constructed with non-combustible construction material and serving total population of 1400. Assume area of each floor as 9800 ft2. Using following formulas: [5 Marks]
a). Insurance Services Office Formula
b). Equation for National Board of Fire Underwriters
c). If fire water demand is required for 4 hours calculate the volume of water storage tank in m3 (For Part b only)
Instructions: Find the values of required parameters from class notes or course book.
Also use 1 gallon = 7.8 Liter.

Given an unconfined aquifer with a saturated thickness of 15 m,
h0, as shown in Fig. 1. Observation wells are located at the radial
distances of 30, 60, and 120 m from the center of pumping
well.
Water is pumped at the rate of 0.015 m^3/sec. After pumping 12
hours, the drwdowns are z1=0.60 m at the radius r1= 30 m , z2 =
0.43 m at r2 = 60 m and z3= 0.26 m at r3 = 120 m.
1. Evaluate the permeability of the aquifer using all three
combinations of selecting two observation wells in the
computation.
2. How many laboratory permeability tests would be required to achieve the accuracy?
