You work for a company that manufactures centrifugal pumps, and you are part of an engineering team that is responsible for improving the productivity. The company is planning to upgrade their single impeller centrifugal pump manufacturing machine at an investment of $(350,000+5000*X) (here, X is the last digit of your student number). The new machine has additional capacity to manufacture (12-X) pumps per hour and consumes (15+ 0.2*X) % less electrical energy. The energy consumption of existing machine is (75 + X) kWh for every hour of operation and electricity tariff is $(0.12 + 0.01*X) cents per kWh. Consider the profit after overhead to be $(1.5 + 0.1*X) per pump and the projected annual demand is equal to the increased production capacity, when operated for 260 days for (8 + 0.1*X) hours daily. Calculate period of operation (in hours/year), energy savings (in kWh/year and $/year), annual increase in production (in pumps/year), annual extended profit on sales (in $/year) and total savings (in $/year). Calculate the discount rate (in %) on the saving, if inflation rate is (1.5 + 0.1*X)% and the life of the machine is (15+0.5*X) years. Consider zero salvage value of the machine, since the resale of such machine is uncertain. If the bank term deposit interest is assumed to remain constant at (3.8+ 0.1*X)% for next 15 years, is it worth investing in this machine?
