Answer:
They will need 200kg of pine logs.
Gauge pressure in the tank = 24045.29 Pa
Absolute pressure= 125370.29Pa
Step-by-step explanation:
Full question:sp.gr=0.8.The fluid in the nanometer is ethyl iodide with sp.gr =1.93. The manometric fluid height is 50 inches. What is the gauge pressure and absolute pressure in the tank?
Converting 50inches to metres. Multiply by 0.0254
50×0.0254=1.27m
Gauge pressure in tank is given by:
P = pgh
Where p= density,g= acceleration due to gravity, h= height
P= 1.93× 1000× 9.81× 1.27= 24045.29Pa
Absolute pressure=Ptotal= Pliquid + Patm
Absolute pressure =24045.29 + 101325=125370.29pa
Step-by-step explanation:
the fence = the perimeter of the rectangle = 200 ft.
and the perimeter of a rectangle is
perimeter = 2×length + 2×width
length = width + 2
so,
200 = 2×(width + 2) + 2×width = 2×width + 4 + 2×width
196 = 4×width
width = 196/4 = 49 ft
Answer:
Ellen spent $2.40 on her lunch.
Step-by-step explanation:
Let,
x be the total amount Ellen had.
Amount spent on lunch =
Amount left after lunch =
Amount spent on movie =
Amount she has left = $1.20
Total amount = Lunch amount + Movie amount + Amount left
x =
Amount spent on lunch = = $2.40
Hence,
Ellen spent $2.40 on her lunch.
