Question

A simple turbomachine is constructed from a disk with two internal ducts which exit tangentially through square holes, as in Fig. $\mathrm{P} 3.117 .$ Water at $20^{\circ} \mathrm{C}$ enters normal to the disk at the center, as shown. The disk must drive, at $250 \mathrm{r} / \mathrm{min},$ a small device whose retarding torque is $1.5 \mathrm{N} \cdot \mathrm{m} .$ What is the proper mass flow of water, in $\mathrm{kg} / \mathrm{s} ?$

Name: A simple turbomachine is constructed from a disk with two internal ducts which exit tangentially through square holes, as in Fig. P 3.117 . Water at 20^∘C enters normal to the disk at the center, as shown. The disk must drive, at 250 r / min, a small device whose retarding torque is 1.5 N·m . What is the proper mass flow of water, in kg / s ?

Step 1

First, we need to find the angular velocity of the disk in rad/s. We are given the rotational speed in rpm (revolutions per minute), so we can convert it to rad/s using the following conversion factor: $$ \omega = 250 \frac{\text{rev}}{\text{min}} \times Show more…
