Final answer:
To calculate the torque applied to the fan, we need the power consumption and angular velocity. The efficiency of the modulation drive unit can be found by comparing the power input and power output. The power consumption of the fan can be estimated by multiplying the power input by the operating time. Predicting the airflow generated by the fan is not possible without more specific information.
Step-by-step explanation:
To calculate the torque applied to the fan, we can use the formula: Torque = Power / Angular Velocity. Since we are given the input speed in rpm and the power is not specified, we cannot directly calculate the torque. However, if we have the power consumption of the fan, we can use that information to estimate the torque applied. To determine the efficiency of the modulation drive unit, we need to know the power input and the power output of the unit. Efficiency can be calculated using the formula: Efficiency = (Power Output / Power Input) x 100%. The power consumption of the fan can be estimated by multiplying the power input by the time the fan is operating. Power Consumption = Power Input x Time. Predicting the airflow generated by the fan is a complex task that requires detailed knowledge of the fan's design, blade shape, and various other factors. It is not possible to accurately predict the airflow without specific information about the fan.
