The cost estimate of a project is $3.5 million. Annual costs for maintaining and operating the facility are forecast as $250,000 per year. After 8 years, it is anticipated the facility will be sold for $2.0 million. If the owner requires a 15% return on his or her investment, what net annual income must be received to recover the capital investment of the project?
Kerosene at 20°C flows at 20 m3 /h in an 8-cm-diameter pipe. The flow is to be metered by an ISA 1932 flow nozzle so that the pressure drop is 7000 Pa. What is the proper nozzle diameter?
