NATURAL GAS ENGINEERING - QUESTION 26.1 : (a) In natural gas pipe sizing, the length of the pipe from the gas source metre to the farthest appliances is 60 feet. The maximum capacities for typical metallic pipes of 60 feet in length are : 66 cubic feet per hour for pipe size of 0.5 inches; 138 cubic feet per hour for pipe size of 0.75 inches; 260 cubic feet per hour for pipe size of 1 inch. By using the longest run method : (i) Find the best pipe size needed for the capacity of 75 cubic feet per hour. (ii) Estimate the suitable range of capacities for the pipe size of 1 inch. (b) The maximum capacities for typical metallic pipes of 50 feet in length are : 73 cubic feet per hour for pipe size of 0.5 inches; 151 cubic feet per hour for pipe size of 0.75 inches; 285 cubic feet per hour for pipe size of 1 inch. By using the branch method find the best pipe size needed for the capacity of 75 cubic feet per hour when the length of the pipe from the gas source metre to the appliance is 52 feet.

NATURAL GAS ENGINEERING - ANSWER 26.1 : (a)(i) Best pipe size needed = 0.75 inches for the capacity of 75 cubic feet per hour. Data for a metallic pipe of 60 feet in length and maximum capacity of 138 cubic feet per hour instead of 66 cubic feet per hour are selected. (ii) Range is more than 138 but less than or equal to 260 cubic feet per hour for pipe size of 1 inch. (b) Best pipe size needed = 0.75 inches for the capacity of 75 cubic feet per hour. Data for a metallic pipe of 60 feet in length instead of 50 feet and maximum capacity of 138 cubic feet per hour instead of 66 cubic feet per hour are selected.
