A nozzle is a device for increasing the velocity of a steadily flowing stream. At the inlet to a certain nozzle, the enthalpy of the fluid passing is 3000 kJ/kg and the velocity is 60 m/s. At the discharge end, the enthalpy is 2762 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. Calculate:
a. The velocity of the fluid at the exit

An alloy contains two metals X and y of densities 4x10^3 and 6x10^3. Find the densities of the alloy given that the volume of X is thrice the volume of Y.

For a platinum wire, the coefficients of variation of resistance with temperature are α=3.94×10^(–3) °C^(–1)
and β=–5.82×10^(–7) °C^(–2).
A thermometer is fabricated using
this wire with
R0=12.00 Ω
where
R0 signifies the resistance of the material of wire
at ice point. When the thermometer is placed in contact with a heat bath, the
resistance is found to be
15.20Ω.
Calculate the temperature of the bath.

How many degrees of freedom does the gas molecules have if under standard
conditions the gas density is 1.3 kg m
^(–3)
and the velocity of sound in it is
v = 330 m s^(–1) .

A box of volume 1 cm3
contains
5.2×10^21
electrons. Calculate their Fermi
momentum and Fermi energy.
Take: me=9.1×10^(–28) g
mn=1.67×10^(–24) g
h=6.62×10^(–27) ergs

Two separate containers filled with different gases. If these gases are allowed to mix,
obtain an expression for entropy of mixing per mole of the mixture. Does the entropy
decreases in the process of mixing of two gases?
