- Product of combustion is used as working substance
- Combustion of fuel takes place inside the cylinder
- Petrol or diesel is used as fuel
- Works on diesel or otto cycle
Correct

Option b is not correct because, it does not include open cycle gas turbines which also consider as IC engines where combustion takes place in separate combustion chamber. So the most appropriate answer is (1)

A turbine is working under a head of 200m. The power developed by the turbine is 100KW and discharge through turbine is 0.125m³/sec. What will be the ratio of unit power to unit discharge for the turbine?
- 4000
- 16000
- $160\times 10^{3}$
- $800\times 10^{3}$
Correct

Unit power

$P_{u}=\frac{P}{H^{\frac{3}{2}}}$

Unit discharge , $Q_{u}=\frac{Q}{\sqrt{H}}$

Ratio = $\frac{P_{u}}{Q_{u}}=\frac{P\times \sqrt{H}}{H^{\frac{3}{2}\times Q}}=\frac{P}{QH}$ = 4000

Incorrect

Unit power

$P_{u}=\frac{P}{H^{\frac{3}{2}}}$

Unit discharge , $Q_{u}=\frac{Q}{\sqrt{H}}$

Ratio = $\frac{P_{u}}{Q_{u}}=\frac{P\times \sqrt{H}}{H^{\frac{3}{2}\times Q}}=\frac{P}{QH}$ = 4000

The equation of the integral curve that passes through (1,2) of the differential equation

y' = $\frac{2x}{y^{2}+1}$
- $2(x^{2}-1)=y^{3}-3y$
- $3x^{2}+11=y^{3}+3y$
- $y^{3}+1=3x^{2}+17$
- None of these
Correct

$\frac{\mathrm{dy}}{\mathrm{d}x}=\frac{2x}{y^{2}+1}$

$\Rightarrow (y^{2}+1)-dy-2xdx=0$ ,the above equation is exact

Integrating we get ,

$\frac{y^{3}}{3}+y-x^{2}=C$

At (1 , 2) , C = $\frac{11}{3}$

$\therefore$ The integrating curve is $y^{3}+3y-3x^{2}=11$

- tan-1 (s-1)
- cot-1 (s-1)
- cos-1 (s-1)
- cosec-1 (s-1)
Correct

$L\left ( \frac{f(t)}{t}\right)=\int_{S}^{\infty}\bar{f}(s)ds$

Where ,
$\bar{f}(s)$ = L(f(t)).

$L\left (\frac{\sin t}{t}\right)=\int_{S}^{\infty}\frac{1}{1+S^{2}}ds$

$\cos t^{-1}S\: ,L\left [e^{t} \left(\frac{\sin t}{t}\right)\right ]=\cot^{-1}(S-1)$
