Question 1 A 3-in. nominal steel pipe of schedule 80 Carrie's saturated water at a temperate of 20°C at a given point 1. At this point, the water flows at 20 litre per second. The water enters a boiler and exists as saturated steam at 120°C and at a height of 50 m above point 1. If the exit pipe from the boiler is a 2-in. Nominal steel pipe of schedule 40, how much heat must be per kg of steam? Ignore all frictional losses.
Question 1
A 3-in. nominal steel pipe of schedule 80 Carrie's saturated water at a temperate of 20°C at a given point 1. At this point, the water flows at 20 litre per second. The water enters a boiler and exists as saturated steam at 120°C and at a height of 50 m above point 1. If the exit pipe from the boiler is a 2-in. Nominal steel pipe of schedule 40, how much heat must be per kg of steam? Ignore all frictional losses.
Question 2
In a portable water treatment plant, water is flowing at steady state and 90°C at a rate of 0.0566 m³/a through a 60° sloping reducing bend. The inlet pipe diameter is 0.1016 m and the outlet 0.0762 m. The friction loss is the pipe bend can be estimated as v²/5. Neglect gravity forces. The exit pressure P2= 111.5 kN/m² gage . Draw a labelled schematic of this piping system, calculate the forces and the resultant force on the bend in newtons.
