In a P-V diagram (for an ideal gas), an isothermal curve will coincide withan adiabatic curve (through a point), when?
Answer: Option 2 The slope of isothermal process in $$p-v$$ plane is \[\frac{{dP}}{{dV}} = \frac{{ - P}}{V}\] The slope of adiabatic process in $$P-V$$ plane is \[\frac{{dP}}{{dV}} = - \gamma \frac{P}{V}\] \[...

The brake power (B.P.) of the engine is given by (where W = Brake load or dead load in newtons, l = Length of arm in meters, N = Speed of engine in r.p.m., S = Spring balance reading in newtons, D = Dia. of brake drum in meters, and d = Dia. of rope in meters)?
Answer: Option 4 The brake power (B.P.) of the engine is given by -B.P = (Wl × 2πN)/60 watts -B.P = [(W - S) πDN]/60 watts - B.P = [(W - S) π...
