1. Depreciation of water cutting equipment

The average purchase price of the waterjet cutting machine is calculated as 2.75 million yuan.

The normal service life is 10 years.

The actual number of working days per year is 300, the average use time per day is 10 hours, and the accumulated working time in 10 years is 30000 hours.

The average replacement cycle of important parts is 3000 hours, and the cost is about 36500 yuan.

The equipment purchase cost and replacement cost are (275 + 3.65×30000 / 3000 =) 3.115 million yuan.

So, the equipment depreciation is about 103.8 yuan per hour.
