High-resolution thermal expansion measurements under helium-gas pressure
(2012-08-01)
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4K ≤ T ≤ 300K and hydrostatic pressure P ≤ 250MPa. Helium ( 4He) is ...

Measuring air pressure with a polymeric gas sensor
(Sociedade Brasileira de Química, 2010)
In this communication we describe the application of a conductive polymer gas sensor as an air pressure sensor. The device consists of a thin doped poly(4'-hexyloxy-2,5-biphenylene ethylene) (PHBPE) film deposited on an ...

Estudo da aplicação da norma NR13 para vasos de pressão P190 em condomínios residenciais
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEspecialização em Engenharia do TrabalhoUTFPR, 2017-05-31)
Most residential condos have an LPG (Liquefied Petroleum Gas) gas central. This central is composed of a series of pressure vessels, commonly called canisters. One of the most common is the P190 pressure vessel with capacity ...
Entropy variation in isothermal fluid flow considering real gas effects
(2011-01-01)
The present paper concerns on the estimative of the pressure loss and entropy variation in an isothermal fluid flow, considering real gas effects. The 1D formulation is based on the isothermal compressibility module and ...
