For Science fair project you can do convection current
Explanation:
Show how to do the process
and then make a model to demonstrate
Materials required:
Potassium Permanganate,beaker,bunsen burner,water and retort stand
Answer:
42.4m/s
Explanation:
To develop the problem it is necessary to apply the concepts related to thermodynamic work and Bernoulli's principle in which the behavior is described of a liquid moving along a stream.
The work of an incomprehensible liquid is given by the equation,
Where,
= Mass flow
= Specific Volumen
P = Pressure
Our values are given by,
= 2kW
Table 1 for saturated water in 10°C
We need to find the mass flow, then re-arrange for
To find the Spray velocity, we apply Bernoulli equation, because at the Nozzle there is not Work or Heat transfer related. Then,
Therefore the spray velocity is 42.4m/s
Answer
given,
distance between A and B is equal to 5 m
let x be the distance of loud speaker from the source A
For constructive interference, path difference = mλ
x - (5 - x ) = 0 , for m = 0
2 x - 5 = 0
2 x = 5
x = 2.5 cm
For destructive interference
m = 0
x = 4 , 1 cm
