This project will incorporate the concepts that apply to the study of fluid mechanics. During this project, you will calculate flow and loss across the system at various points in the system.
Overview
You are working as a Manufacturing Engineer at a production plant for E-Magine Biomedical, a manufacturer of hospital beds. One of the oil coolers in the plant needs to be redesigned and re-routed.
Instructions
The specifications of the oil cooler with a bypass are given below.
Specifications:
The total length of pipe in the three inch
anch is 10 ft, and the length of pipe in the one inch
anch is 8 ft.
Brine (sg=1.04, m=10-3 Pa*s) flows at 250gpm through the entrance at point A.
Assume fully tu
ulent flow in both
anches (f=ft).
Pipes are standard Schedule 40 steel pipes.
Assume the globe valve is partially shut so its equivalent L/D is 1000.
For Part 1 of this project, you are tasked with determining the following:
The flow rate in both
anches
The pressure drop in both
anches
The overall resistance coefficient
Part 2 of project task is to specify a suitable pump and determine operating conditions based on the information provided to you in the Course Project Part 1 and the information below. The pump will fulfill the design requirements for the system shown in the figures below. It is a combination series/parallel system that operates as follows:
Brine at 160°F (SG=1.04, m=10^-3 Pa*s) is drawn at a minimum rate of 250 gal/min from a tank
into the 4-in suction line of the pump. The suction line has a total length of 10 ft.
The 3-in discharge line elevates the water 15 ft to the level of a large heat exchanger. The
discharge line has a total length of 40 ft.
The flow splits into two
anches with the primary 3-in line feeding a large heat exchanger that
has a K-factor of 12 based on the velocity head in the pipe. These
anches were examined in
Part 1 of the project.
Determine the system resistance operating curve for the system.
All pipes are Schedule 40 steel.
For this system, operating at the desired operating conditions, determine the following:
a. The pressure at the pump inlet
. The NPSH available at the pump inlet
c. The pressure at point A before the
anches
d. The volume flow rate through the heat exchanger line
e. The volume flow rate through the bypass line
f. The total head on the pump
g. The power delivered to the water by the pump. Then specify a suitable pump for this system
that will deliver at least the desired 250 gal/min of flow.
h. For the selected pump, determine the following:
XXXXXXXXXXThe actual expected flow rate produced by the pump at the operating point
XXXXXXXXXXThe power input to the pump
XXXXXXXXXXThe NPSH required
XXXXXXXXXXThe efficiency at the operating point.
NOTE: This project can be accomplished using computer aided design software described in the course.
