Answer:
1 - Define the problem
2. Do background Research
3 - Specify the requirements needed to fix/solve/complete the task at hand
Hope this helps!
Explanation:
1. The problem must be know before anything can be done
2. Do background Research to find if this issue has been solved or what can be done to solve it
3 - Find the requirements needed to fix the issue (ex. Size of replacement part)
Given Information:
Temperature = T₁ = 50 °C
Mass flow rate = m = 30 kg/s
Exit Pressure = P₂ = 1.5 MPa = 1500 kPa
Required Information:
Power = P = ?
Answer:
Power = 45.16 kW
Explanation:
The power of the pump can be found using,
P = m*W
Where m is the mass flow rate and W is the work done by pump.
Work done is given by
W = vf*(P₂ - P₁)
Where vf is the specific volume and its value is found from the saturated water temperature table.
at T = 50 °C
vf = 0.001012 m³/kg
P₁ = 12.352 kPa
P = m*W
P = m*vf*(P₂ - P₁)
P = 30*0.001012*(1500 - 12.352)
P = 45.16 kW
Answer:
(D) Unlike traditional techniques, 3-D printing results in some wasted material.
Explanation:
3-D printing :
1. It is also known as additive manufacturing.
2. It can use for complex shape printing.
3.It is generally use in fashion areas.
4. In this printing method wasted material is very low as compare to traditional printing.
5.It is use CAD system for printing.
So the option D is correct.
(D) Unlike traditional techniques, 3-D printing results in some wasted material.
