Answer:
17.658 kPa
Explanation:
The hydrostatic pressure of a fluid is the weight of a column of that fluid divided by the base of that column.
Also, the weight of a column is its volume multiplied by it's density and the acceleration of gravity:
Meanwhile, the volume of a column is the area of the base multiplied by the height:
Replacing:
The base cancels out, so:
The pressure depends only on the height of the fluid column, the density of the fluid and the gravity.
If you have two point at different heights (or depths in the case of objects submerged in water) each point will have its own column of fluid exerting pressure on it. Since the density of the fluid and the acceleration of gravity are the same for both points (in the case of hydrostatics density is about constant for all points, it is not the case in the atmosphere), we can write:
We do not know at what depth the man of this problem is, but it doesn't matter, because we know the difference in height of the two points of interes (h1 - h2) = 1.8 m. So:
Answer: Forward So it's D
The advantage of a foundation slab is extensive or complex form work isn't required. The correct option is d.
<h3>What is a foundation slab?</h3>
A foundation slab is a slab that is constructed beneath the house underground. These slabs made the houses above the ground and there is enough space present below the house.
This space can be used for the wiring and other fittings of the house, so it is useful for the house for further construction.
Therefore, the correct option is d. Extensive or complex form work isn't required.

Answer:
The exit temperature of hot water =200.005°F
Explanation:
Given that
Volume flow rate of water = 20 gpm ⇒
Volume flow rate of water =
inlet temperature of water = 200°F
Heating load = 92.000 Btu/hr ⇒ Heating load= 0.0269 KW
We know that mass flow rate is given as
So mass flow rate of water = 1000 x 0.00126 Kg/s
mass flow rate of water= 1.26 Kg/s
Now by balancing heat
Heating load =
=200.005°F
So the exit temperature of hot water =200.005°F
Answer:
Opened Push-button Switch (i.e. a PTM Switch)
Explanation:
Tha's just another symbol for a switch, but this one specifies that the switch is a push-button type of switch.
Since it's not touching and completing the line, the state of the switch is initially open.
