#### Answer

It reaches specifications for the time to start up, starting up in 53 seconds, but it does not have 96 percent efficiency.

#### Work Step by Step

We see how long it takes to get to 17 rpm:
$\alpha=\frac{\tau}{I}=\frac{896,000\ Nm}{2.65\times10^7 \ kgm^2}=.034\ rads/s^2$
17 rpm equals 1.78 radians per second, so it follows:
$\Delta t =\frac{1.78\ rads/s}{.034\ rads/s^2}=53 \ seconds $
We now see about efficiency specifications:
We find the power:
$P=\frac{I\omega^2}{2t}=\frac{2(2.65\times10^7)(1.78)}{2(53)}=8.96\times10^5$
96 percent of 1.5 is 1.41, not .896, so the turbine is not meeting efficiency specifications.
