Answer:
flow(m) = 7.941 lbm/s
Q_in = 90.5184 Btu/lbm
Q_out = 56.01856 Btu/lbm
Explanation:
Given:
- T_1 = 60 F = 520 R
- T_6 = 940 = 1400 R
- Heat ratio for air k = 1.4
- Compression ratio r = 3
- W_net,out = 1000 hp
Find:
mass flow rate of the air
rates of heat addition and rejection
Solution:
- Using ideal gas relation compute T_2, T_4, T_10:
T_2 = T_1 * r^(k-1/k)
T_2 = T_4 = T_10 = 520*3^(.4/1.4) = 711.744 R
- Using ideal gas relation compute T_7, T_5, T_9:
T_7 = T_6 * r^(-k-1/k)
T_7 = T_5 = T_9 = 1400*3^(-.4/1.4) = 1022.84 R
- The mass flow rate is obtained by:
flow(m) = W_net,out / 2*c_p*(1400-1022.84-711.744+520)
flow(m) = 1000*.7068 / 2*0.24*(1400-1022.84-711.744+520)
flow(m) = 7.941 lbm/s
- The heat input is as follows:
Q_in = c_p*(T_6 - T_5)
Q_in = 0.24*(1400 - 1022.84)
Q_in = 90.5184 Btu/lbm
- The heat output is as follows:
Q_out = c_p*(T_10 - T_1)
Q_out = 0.24*(711.744 - 520)
Q_out = 56.01856 Btu/lbm
Viscosity isT=u(U/y) where T is shear stress & u is velocity and y is thr length
The answer is =2.57
GPS device details are given below.
Explanation:
Even a simple GPS unit has a wide range of settings and features. Because every unit’s operation varies, this article won’t provide step-by-step details. Read the owner's manual to familiarize yourself with it..
If you’d like additional help, you can also sign up for a GPS navigation class at an REI store.
Though steps vary, all GPS receivers do the following basic functions:
Display position: A GPS tells you where you are by displaying your coordinates; it also shows your position on its base map or topo map.
Record tracks: When tracking is turned on, a GPS automatically lays down digital bread crumbs, called “track points,” at regular intervals. You use those later to retrace your steps or to evaluate the path you traveled.
Navigate point-to-point: A GPS directs you by giving you the direction and distance to a location, or “waypoint.” You can pre-mark waypoints by entering their coordinates at home. In the field you can have the unit mark a waypoint at a place you'd like to return to, such as the trailhead or your campsite. A GPS unit provides the bearing and distance “as the crow flies” to a waypoint. Because trails don’t follow a straight line, the bearing changes as you hike. The distance to travel also changes (decreasing, unless you’re heading the wrong direction) as you approach your goal.
Display trip data: This odometer-like function tells you cumulative stats like how far you’ve come and how high you’ve climbed.
GPS and your computer: GPS units come with a powerful software program that lets you manage maps, plan routes, analyze trips and more. Invest the time to learn it and to practice using all of its capabilities.
Answer:
A sole proprietorship, also known as the sole trader, individual entrepreneurship or proprietorship, is a type of enterprise that is owned and run by one person and in which there is no legal distinction between the owner and the business entity.
Explanation:
Answer:
The required bulk modulus is 
Psi. So, the answer is non of these.
Explanation:
Change in pressure of the fluid is directly proportional to the volumetric strain. The constant of proportionality is the bulk modulus of the fluid.
Step1
Given:
Percentage change in volume is 1%.
Change in pressure is 10000 Psi.
Calculation:
Step2
Volumetric strain is calculated as follows:
Step3
Bulk modulus is calculated as follows:
\frac{\bigtriangleup V}{V}=0.01
K = 1000000 Psi.
Thus, the required bulk modulus is Psi.
