In any energy transfer, not all of the energy will be transferred as useful energy. Some energy transfers will be non-useful, such as heat transfer to the surroundings (as is the case here): It is assumed that all the electrical energy supplied to the heater was transferred to the aluminium block [1 mark] and none was lost / transferred to the ...

• Kinetic energy is proportional to the mass. If a bowling ball and a ping pong ball have the same velocity, the bowling ball has much larger kinetic energy. • Kinetic energy is always positive. • unit : Joule (J) = kg ⋅m 2 /s2 Example: If we drop a 3-kg ball from a height of h = 10 m, the velocity when the ball hits the ground is given by:

From the energy balance equation, qin=wb,out+cv(T2-T1)=-147.5 kJ/kg+(0.3122 kJ/kg⋅K)(444.7-303)K=-103.3 kJ/kg Thus, qout=103.3 kJ/kg #4 4-60 The enthalpy changes for neon and argon are to be determined for a given temperature change. Assumptions At specified conditions, neon and argon behave as an ideal gas. Properties The constant-pressure specific …

Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to
