WHAT is the composition of Urea, and what changes does it undergo after excretion? How much is passed daily by an average adult, and how much would be excreted per annum by a mixed population of 10,000 persons ? 2. How much Sodium Chloride per 100,000 parts is there in sea-water? In a certain part of a tidal river the amount of Sodium Chloride is 5-7 per 100,000, the average proportion of Chlorine in the fresh-water, sewage, &c. that find their way into it is 2 per 100,000; find the proportion of sea-water in the total volume of the stream at the place and time of observation. 3. A circular ward with a dome-shaped roof requires to be measured. The diameter is 36 feet; the height to the centre of the roof is 18 feet, and the height of the walls is 12 feet. Find the floor space and total cubic contents. How many patients would you put in such a ward? Compare the advantages and disadvantages of circular and rectangular wards from a theoretical point of view. 4. It is wished to give 2000 cubic feet of air per head per hour in a room of 8000 cubic feet capacity, occupied by 14 persons; would this be feasible ? How much sectional area of inlet and outlet opening would be required by each individual ? Would the ventilation be sufficient ? 5. Describe a Rain-gauge and the precautions necessary in placing and observing it. What is the average rainfall in England proper ? If $ of an inch of rain falls in 10 minutes, how much water would this give per square mile in 24 hours at the same rate ? State the result in cubic feet, gallons and tons. 6. What is the source of energy in the human frame? How is work usually expressed ? How much work is done by a man walking at an ordinary velocity a distance of 15 miles on an ascent of 1 in 200; weight of man and what he carries 12 stone 8 lbs. ? CLXXVII. A WEDNESDAY, October 3, 1883. 9 A.M. to 12 M. PART I. PAPER II. 1. Of what importance is the determination (a) of Chlorine, (b) of Nitric Acid in a drinking water ? Describe any one method for determining the Nitric Acid. 2. Describe in detail Pettenkofer's process for the estimation of Carbonic Acid in the air; giving an example. 3. Give your opinion, with your reasons for it, on the quality of each of the examples of water which gave the following results on analysis : 4. Classify the various Chemical processes that have been proposed for the purification of Sewage, and discuss the rationale of each. 5. What principles must be followed in the construction and ventilation of House Drains? If a 9 inch drain with a fall of 1 in 200 gives a velocity of 3 feet per second, what fall must it have to give a velocity of 6 feet per second, the drain running half full in each case ? 6. An outbreak of disease takes place in a town of 57,000 inhabitants ; 1340 cases occur in 29 days, and of these 712 die; what are the proportions of cases and of deaths per thousand of the population for the period, and also per annum at the same rate ? |
