tank_design#
Design and cost algorithms from ordinary vessels.
References
- class TankPurchaseCostAlgorithm(f_Cp, V_min, V_max, V_units, CE, material)[source]#
Create a TankPurchaseCostAlgorithm for vessel costing.
- Parameters:
- f_Cp#
Returns the purchase cost given the volume.
- Type:
function
- V_units#
Units of measure for volume.
- Type:
AbsoluteUnitsOfMeasure
Examples
Find the number of mixing tanks and the total purchase cost at a volume of 1 m^3 using the purchase cost equation from [1]:
>>> from biosteam.units.design_tools import TankPurchaseCostAlgorithm >>> TankPurchaseCostAlgorithm(lambda V: 12080 * V **0.525, ... V_min=0.1, V_max=30, V_units='m^3', ... CE=525.4, material='Stainless steel') TankPurchaseCostAlgorithm(f_Cp=<lambda>, V_min=0.1, V_max=30, CE=525.4, material=Stainless steel, V_units=m^3)
- field_erected_tank_purchase_cost(V)[source]#
Return the purchase cost [USD] of a single, field-erected vessel assuming stainless steel construction material.
Notes
The purchase cost is given by [1].
If \(V < 2 \cdot 10^3\):
\(C_p^{2007} = 32500.0 + 79.35 V\)
Otherwise:
\(C_p^{2007} = 125000.0 + 47.1 V\)
Examples
>>> field_erected_tank_purchase_cost(300) 112610.0
- compute_number_of_tanks_and_purchase_cost(total_volume, purchase_cost_algorithm)[source]#
Return number of tanks and purchase cost of a single tank.
- Parameters:
total_volume (float) – Total volume required [m^3].
purchase_cost_algorithm (TankPurchaseCostAlgorithm) – All costing options.
