Vater (20°C) is pumped through the 300-mm steel pipe from the lower tank to the upper one at a rate of 0.4 m³/s. Given that the pump efficiency is 65% and the pump is on for 5 hours each day, what will be the monthly (30 days) energy cost for the pump if the electricity rate is 0.5 USD per kWh?

Lubricants

Lubricant can be expressed as the substance that is applied among surfaces to control the wear and tear and improve performance. Lubricants play an essential part in the safety of machinery components like gears, shaft, linkage, cam, clutches, and many others. The quantities which affect the amount of lubricant are temperature, surrounding conditions, speed of the components, and many more.
