An indicator diagram, taken from petrol engine during a test, was divided into 8 strips of equal width. The mid ordinates of the strips measured 17.5, 20.0, 18.75, 12.5, 10.0, 7.5, 5.0,

and 3.75. The scale of the spring used was 60 kPa/mm. Determine the mean effective pressure

of this engine. If the engine cylinder is 80 mm in diameter and 120 mm in stroke, calculate the

net work of the engine per stroke.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

where’s the list ? the question is incomplete

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

option number c is the right answer.
