Height of Specimen Solution

Follow our step by step solution on how to calculate Height of Specimen?

FIRST Step Consider the formula

H sp = \frac{PN \cdot ρ \cdot A \cdot t p}{V}

Next Step Substitute values of Variables

∴

H sp = \frac{4.36H/m \cdot 0.0385kgf/m² \cdot 0.002m² \cdot 3s}{0.002m³}

Next Step Convert Units

∴

H sp = \frac{4.36H/m \cdot 0.3776Pa \cdot 0.002m² \cdot 3s}{0.002m³}

Next Step Prepare to Evaluate

∴

H sp = \frac{4.36 \cdot 0.3776 \cdot 0.002 \cdot 3}{0.002}

Next Step Evaluate

∴

H sp = 5.00510164989414m

LAST Step Rounding Answer

∴

H sp = 5.0051m

How to Evaluate Height of Specimen?

Height of Specimen evaluator uses Specimen Height = (Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)/Volume of Air Flow Through Specimen to evaluate the Specimen Height, The Height of Specimen in a casting process is determined by the product of the permeability number, pressure exerted, cross-sectional area, time, and the reciprocal of the volume of air. Specimen Height is denoted by H_sp symbol.

How to evaluate Height of Specimen using this online evaluator? To use this online evaluator for Height of Specimen, enter Permeability Number (PN), Air Pressure on Wall (ρ), Cross-Sectional Area of Specimen (A), Time (t_p) & Volume of Air Flow Through Specimen (V) and hit the calculate button.

FAQs on Height of Specimen

What is the formula to find Height of Specimen?

The formula of Height of Specimen is expressed as Specimen Height = (Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)/Volume of Air Flow Through Specimen. Here is an example- 5.005102 = (4.36*0.377556024999973*0.002027*3)/0.002.

How to calculate Height of Specimen?

With Permeability Number (PN), Air Pressure on Wall (ρ), Cross-Sectional Area of Specimen (A), Time (t_p) & Volume of Air Flow Through Specimen (V) we can find Height of Specimen using the formula - Specimen Height = (Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)/Volume of Air Flow Through Specimen.
