Answer:

The answer is 5174400 J.

Explanation:

Here you have to keep in mind the equation to determine the amount of heat  (Q) that one body of mass <em>m </em>can take. The equation is : [tex] Q=mc\Delta T [\tex]

where <em>m</em> is the mass, <em>c</em> is the specific heat and [tex] \Delta T [\tex] the temperature variation. This way: Q=1400kg*3.52J/gºC*(28.5-27.45) ºC=1400000 g*3.52 J/gºC * (28.5-27.45)ºC=5174400J=5174.4 kJ=5.17 MJ.

Two pipes move the same amount of ideal fluid in the same amount of time. One pipe has a 2 in. diameter; the other has a 3 in. d
xxTIMURxx [149]
By Bernoulli Theorem, We know, that for any two points in the pipe, total energy would be same. 

Pressure Energy + K.E. of 1st pipe = Pressure Energy + K.E. of 2nd pipe
[ No need to consider Potential energy as height isn't mentioned] 
P₁ + mv₁²/2 = P₂ + mv₂²/2

So, we know, P + mv²/2 = constant

As value of kinetic energy is larger in larger in 2 in. pipe [ 'cause area is indirectly proportional to velocity ], Value of pressure energy would be smaller in it. So, pressure energy will be higher in the pipe of 3 in.

In short, option A would be your correct answer.

Hope this helps!
