A 10-inch blow-out cock is fitted to carry off the water from two boilers; find the dimensions of the pipe from each boiler, the two together having the same area as the blow-out cock. 24. A double-acting air-pump is to be substituted for a singleacting one; if the diameter of the latter is 2 feet, what must be the diameter of the former, if the stroke remains the same? 25. The stroke of a double-acting air-pump is the same as that of the steam-piston, and the diameter of the bucket is 30 inches; if the stroke had been half that of the former, what should have been the diameter 1 26. A plunger feed-pump is 7 inches in diameter, and that of plunger 4 inches; if the depth of the cylinder be 21 inches, and the stroke of the plunger be 20 inches, what portion of the contents of the cylinder will be expelled at each stroke 1 27. How many tons of coal are there in a heap 60 by 40, and 24 feet high, if a ton can be contained in a box 3 feet high, whose base is a square 4 feet by 4? 28. Find the internal and external pressure on the cylindercover of an engine whose diameter is 94 inches, the steam-gauge standing at 20 inches, and the condenser-gauge at 26 inches. 29. What will be the loss of pressure on a piston of 80 inches in diameter, from shutting off the injection water, if the condenser-gauge had stood at 27 inches previously? 30. The cubic contents of a cylinder are to be 8000 cubic inches, and the stroke must not exceed 2 feet; what must be its diameter 1 31. A boiler generates 16,000 cubic feet of steam per hour; what number of revolutions must an engine make per minute, the diameter of the cylinder being 30 inches, and length of stroke 2 feet, that it may utilise all the steam, if it be cut off at the...
