9. Liquid benzene at 20°C is to be pumped from a storage tank to a chemical reactor through 165 ft of 2-in Schedule 80 steel pipe followed by 100 ft of 3-in Schedule 80 pipe to the pump. The discharge line from the pump to the reactor consists of 230 ft of 3-in Schedule 80 pipe. The 2- in pipe includes a fully open globe valve while the 3-in pipe includes 2-45° elbows, 2-90° elbows and a fully open globe valve. The reactor is located 300 ft above the liquid level in the storage tank. The tank is vented to the atmosphere and the reactor operates at a pressure of 58psig. Calculate the annual pumping cost if power costs PHP 2.48 per kW-hr if flow is maintained at 155 gal/min. The pump has an efficiency of 55% and it operates for 300 days a year.
