during a human heart beat, 20g of blood are pushed into the main arteries. This blood is accelerated from a speed of 0.2m/s to 0.34m/s. For a heart pushing at 70bpm, calculate the average power of the heart pump
The formula for calculating average power is average power (P) = total work (W) / total time (t).
The unit of measurement for average power is watts (W).
Average power is the total amount of work done divided by the total time, while instantaneous power is the power at a specific moment in time. Average power takes into account the entire duration of an activity, while instantaneous power only reflects a single moment.
The factors that can affect the calculation of average power include the amount of work done, the duration of the activity, and the efficiency of the system or device. Other external factors such as friction and air resistance can also affect the calculation.
Average power can be used in various practical applications such as calculating the energy consumption of household appliances, determining the power output of an engine or motor, and analyzing the performance of athletes during physical activities. It is also a crucial factor in understanding and improving the efficiency of different systems and devices.
