The volume of a cylinder is to be determined from measurements of the diameter and length. If the length and diameter are measur
sveta [45]

Answer: The uncertainty in the measurements is 4%

Explanation: uncertainty is the doubt or level of not being sure about an outcome or a result.

Because the volume of the cylinder is gotten by measuring length and diameter of the cylinder, using a micrometer that has a 0.5% uncertainty, this will cause the measurements of each value to have a 0.5% uncertainty.

Therefore, since the length has 0.5% uncertainty and the diameter has 0.5% uncertainty too.

The uncertainty in the measurement will be.

0.5% + 0.5% = 1%

Since we are told that this measurement was carried out in four different locations, that means the uncertainty will become;

1% × 4 = 4%

As the number of locations increases, the uncertainty in the measurement will increase as well.

Steam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s, and leaves at 300°C and 200 kPa while losing heat at a rat
jeyben [28]

Answer:606 m/s

Explanation:

Given

Steam Inlet temperature 400^{\circ} C and pressure 800 KPa

h_1=3267.7 kJ/kg

initial Velocity 10 m/s

Steam Outlet Velocity is 300^{\circ} C and pressure is 200 KPa

h_2=3072.1 kJ/kg

\nu _2=1.31632

From steam table

Heat loss 25  KW

inlet area 800 cm^2

applying Steady Flow Energy Equation

h_1+\frac{1}{2}v_1^2++Q=h_2+\frac{1}{2} v_2^2+W

3267.7+\frac{1}{2000}10^2-25=3072.1+\frac{1}{2000}v_2^2

3267.7-3072.1+0.05-25=\frac{1}{2}v_2^2

v_2=\sqrt{195.65\times 2}=606 m/s

and volume flow rate is m=\dot{m}\mu _2=2.082\times 1.31623=2.74 m^3/s
