<p>Muhammad,</p>
<p> Type534 makes the fundamental assumption that the liquid
properties (density, specific heat, viscosity, and thermal
conductivity) are constant in the temperature/pressure range over
which the tank is operated. I'd suggest you find the values of
those properties at 4MPa and 250C and again at 8MPa and 300C. If
the properties change only a little then you can use Type534. <br>
</p>
<p> The same assumption is true for the collector model. If the
fluid properties cannot be assumed to be constant then you might
want to look at some of the components in the High Temperature
Solar library instead.</p>
<p>kind regards,</p>
<p> David</p>

<div>Hi,</div>
<div><br>
</div>
<div>I have to use the type 534 with plugins (Storage tank) for
temperature ranges as high as 250 to 300 degrees Celsius and
pressure around 4 to 8 MPa. Can this type be used for these
ranges. If not is there any other type of storage tank that
can be used.</div>
<div><br>
</div>
<div>Also, I wish to ask if the type 1288 (Linear Fresnel
Collectors) could be used for the ranges mentioned above. </div>
<div><br>
</div>
