How fast must a 70 kg student be running to have a kinetic energy of 568 J?!
Dmitry [639]

Answer: 4.03 m/s

Explanation: Kinetic energy is

KE = 1/2 m v²

So we derive the equation to have v.

v = √ 2KE / m

= 2 x 568 J / 70 kg

= 16.23

= √ 16.23

= 4.03 m/s

Fast-moving glaciers that can move up to 6 kilometers per year
AlladinOne [14]
The answer for this question would be the term SURGING. Surging is the fast-moving glacier that can move up to 6 kilometers per year. I<span>t flows more quickly, sometimes moving 10 to 100 times faster than it normally does. This is one of the classification of a glacier aside from the normal type. Hope this answers your question.</span>

This web page presents a sample report [Herwald, 1999] written in a microprocessor laboratory course at Virginia Tech. In this report, carets (>) are given to reveal the line spacings in the report's format (in an actual report, these carets would not appear). Also, in this report, the actual appendices are not complete (in an actual report, these appendices would be complete, and each would begin on a separate page). Moreover, an aspect of format that is probably not reflected by your browser is that the report's title and appendices' titles are in 14-point type, the subheadings and text are in 12-point type, and the figure captions are in 10-point type. Note that instructors of other laboratory courses may have different expectations as far as the format and style of lab reports in their classes. For instance, the guidelines for many laboratory reports call for an abstract to appear in the report's beginning. Moreover, some instructors frown on the use of the first person (I or we). </span></span>

Air enters an adiabatic compressor at 104 kPa and 292 K and exits at a temperature of 565 K. Determine the power (kW) for the co
ladessa [460]

Answer:

\dot W_{in} = 49.386\,kW

Explanation:

An adiabatic compressor is modelled as follows by using the First Law of Thermodynamics:

\dot W_{in} + \dot m \cdot c_{p}\cdot (T_{1}-T_{2}) = 0

The power consumed by the compressor can be calculated by the following expression:

\dot W_{in} = \dot m \cdot c_{v}\cdot (T_{2}-T_{1})

Let consider that air behaves ideally. The density of air at inlet is:

P\cdot V = n\cdot R_{u}\cdot T

P\cdot V = \frac{m}{M}\cdot R_{u}\cdot T

\rho = \frac{P\cdot M}{R_{u}\cdot T}

\rho = \frac{(104\,kPa)\cdot (28.02\,\frac{kg}{kmol})}{(8.315\,\frac{kPa\cdot m^{3}}{kmol\cdot K} )\cdot (292\,K)}

\rho = 1.2\,\frac{kg}{m^{3}}

The mass flow through compressor is:

\dot m = \rho \cdot \dot V

\dot m = (1.2\,\frac{kg}{m^{3}})\cdot (0.15\,\frac{m^{3}}{s} )

\dot m = 0.18\,\frac{kg}{s}

The work input is:

\dot W_{in} = (0.18\,\frac{kg}{s} )\cdot (1.005\,\frac{kJ}{kg\cdot K})\cdot (565\,K-292\,K)

\dot W_{in} = 49.386\,kW
