Explanation:
Formula: 600K − 273.15 = 326.85°C
Answer:
a) Fi = 85.76 N
b) Fi = 87.8 N
Explanation:
Given:-
- Density of hydraulic oil, ρ = 804 kg/m^3
- The radius of input piston, ri = 0.00861 m
- The radius of output piston, ro = 0.141 m
Find:-
What input force F is needed to support the 23000-N combined weight of a car and the output plunger, when
(a) the bottom surfaces of the piston and plunger are at the same level
(b) the bottom surface of the output plunger is 1.10 m above that of the input plunger?
Solution:-
For part a.
- We see that both plungers are equal levels or there is no pressure due to elevation head. So we are only dealing with static pressure exerted by the hydraulic oil on both plungers to be equal. This part is an application of Pascal's Law:
Pi = Po
Fi / Ai = Fo / Ao
Fi = Ai / Ao * Fo
Fi = (ri/ro)^2 * Fo
Fi = ( 0.00861 / 0.141 )^2 * 23000
Fi = 85.76 N
For part b.
- We see that both plungers are at different levels so there is pressure due to elevation head. So we are only dealing with static pressure exerted by the hydraulic oil on both plungers plus the differential in heads. This part is an application of Bernoulli's Equation:
Pi = Po + ρ*g*h
Where, h = Elevation head = 1.10m
Fi = (ri/ro)^2 * Fo + ρ*g*h*π*ri^2
Fi = 85.76 + (804*9.81*1.1*3.142*0.00861^2)
Fi = 87.8 N
Answer:
The thickness of ring in model is 0.00001 inch and the height of ring is 0.0001 inch.
Explanation:
The radius of Saturn = 60000 km
The thickness of rings = 0.01 km
The height of ring ripples = 100 m or 0.1 km
Now design a new model with a radius of 60 inches.
Therefore, the radius of Saturn (600000 km) = radius of the model (60 inches)
Here, one inch of the model will be equal to 1000 km of Saturn.
1 km of Saturn = 0.001 inch of model
Thickness of ring = 0.01 km
Therefore, thickness of ring in model = 0.01 x 0.001 = 0.00001 inch
The height of Saturn ring = 0.1 km
Therefore, the height of ring in model = 0.1 x 0.001 = 0.0001 inch.
The distance is increasing as time passes.
Answer: Anthony will be warmer after the game.
Explanation :
Anthony and Maelynn are watching a football game outside on a sunny day. Anthony is wearing a black shirt and Maelynn is wearing a white shirt. Anthony will be warmer after the game. The black color is a good absorber of radiation and a bad reflector.
The black color absorbs heat until a thermal equilibrium is attained. So, it is advisable to wear cotton clothes in summers not dark colored clothes.
