Answer:
load = 156 lb/ft
Explanation:
given data
interior wall of a building = 2×4 wood studs
plastered = 1 side
wall height = 13 ft
solution
we get here load so first we get wood stud load and that is
we know here from ASCE-7 norm
dead load of 2 x 4 wood studs with 1 side plaster = 12 psf
and we have given height 13 ft
so load will be = 12 psf × 13 ft
load = 156 lb/ft
Answer
Statically determinate beams are those beams in which the unknown reaction forces are equal or less than the equilibrium equation.
As shown in figure 1 in which reaction forces are 3 and we have 3 equilibrium equation so beam is determinate.
Statically indeterminate beams are those beams in which unknown reaction force are more than the equilibrium equation.
As shown in figure 2 in which reaction forces are 6 and we have 3 equilibrium equation so beam is indeterminate.
Answer:
a) Mechanical efficiency (
)=63.15% b) Temperature rise= 0.028ºC
Explanation:
For the item a) you have to define the mechanical power introduced (Wmec) to the system and the power transferred to the water (Pw).
The power input (electric motor) is equal to the motor power multiplied by the efficiency. Thus,
.
Then, the power transferred (Pw) to the fluid is equal to the flow rate (Q) multiplied by the pressure jump
. So
.
The efficiency is defined as the ratio between the output energy and the input energy. Then, the mechanical efficiency is 
For the b) item you have to consider that the inefficiency goes to the fluid as heat. So it is necessary to use the equation of the heat capacity but in a "flux" way. Calling <em>H</em> to the heat transfered to the fluid, the specif heat of the water and
the density of the water:

Finally, the temperature rise is:

Font of the slide can be edited in the presentations :-
Explanation
By following these steps Su can change the presentation font of her second slide.
1. Edit- As Su open her second slide , there will be a option of "Edit" on the top right corner of the screen.
2. Font- As the various options are available on the screen such as font size , add image etc ,click on the option "Font"
3. Drop Down- As you click on font option , it will be followed by a drop down option with various type of fonts. Su can select the font she wishes to add in her presentation and look it more precise by adjusting the Font Size.
4 Save- Save the changes made in the slide for future.
