Find the amount of energy (Q) required to raise the temperature of the water in kilojoules (KJ).
Given mass of water m = 2kg = 2000g.
Temperature difference ΔΤ = T2 – T1 = 60 °C – 25 °C = 35 °C .
Specific heat of water = 4.18 J/g* °C .
Therefore, Q =
kilo joules.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
