Classical mechanics calculators. Projectile Motion Calculator Acceleration Calculator Kinetic. Basic Thermodynamics Calculators comprises a selection of 35 different calculators that will simplify calculations which have given you headaches so far. Complex calculations, such as Black Body. Calculate the heat and work requirements and ΔU and ΔH of the air for each path. The following heat capacities for air may be assumed independent of temperature: C V = 20.78 and C P =29.10 J mol-1 K-1 Assume also for air that PV/T is a constant, regardless of the changes it undergoes. At 298.15K and 1 bar the molar volume of air is 0.02479 m3.

Here is a simple Heat capacity calculator to calculate the heat generated, measured in Joules, using the values of specific heat, mass and change in temperature. The heat capacity is the amount of heat needed to raise the temperature by 1 degree. Specific heat refers to the amount of heat required to raise unit mass of a substance's temperature by 1 degree. In the below heat calculator, enter the values for specific heat, mass and change in temperature and click calculate.

Thermodynamics calculators give you a list of online Thermodynamics calculators. A tool perform calculations on the concepts and applications for Thermodynamics calculations. These calculators will be useful for everyone and save time with the complex. Thermodynamics is the study of relationships between heat and other forms of energy. It’s technically a branch of physics, and it has reputation as one of the most difficult subjects for university students. While it’s true that thermodynamics can be pretty confusing, there’s no reason you can’t succeed if you’re a diligent student!

Example:

A substance having a specific heat of 8 J/kgoC, mass of 9 gm and change in temperature of 15 C.

First law of thermodynamics calculator

Solution:

Heat Capacity = 8 x 9 x 15
= 1.08 J

Calculate pump hydraulic and shaft power

Hydraulic Pump Power

The ideal hydraulic power to drive a pump depends on

  • the mass flow rate the
  • liquid density
  • the differential height

- either it is the static lift from one height to an other or the total head loss component of the system - and can be calculated like

Basic Thermodynamics Calculators

Ph(kW) = q ρ g h / (3.6 106)

= q p / (3.6 106) (1)

where

Ph(kW) = hydraulic power (kW)

q = flow (m3/h)

ρ = density of fluid (kg/m3)

g = acceleration of gravity (9.81 m/s2)

h = differential head (m)

p = differeential pressure (N/m2, Pa)

The hydraulic Horse Power can be calculated as:

Ph(hp) = Ph(kW) / 0.746 (2)

where

Ph(hp) = hydraulic horsepower (hp)

Or - alternatively

Ph(hp) = qgpm hft SG / (3960 η) (2b)

where

qgpm = flow (gpm)

hft = differential head (ft)

SG = Specific Gravity (1 for water)

η = pump efficiency

Example - Power pumping Water

1 m3/h of water is pumped a head of 10 m. The theoretical pump power can be calculated as

Ph(kW) = (1 m3/h) (1000 kg/m3) (9.81 m/s2) (10 m) / (3.6 106)

= 0.027 kW

Shaft Pump Power

First Law Of Thermodynamics Calculator

The shaft power - the power required transferred from the motor to the shaft of the pump - depends on the efficiency of the pump and can be calculated as

Ps(kW) = Ph(kW)/ η (3)

where

Ps(kW) = shaft power (kW)

η = pump efficiency

Online Pump Calculator - SI-units

The calculator below can used to calculate the hydraulic and shaft power of a pump:

Online Pump Calculator - Imperial units

The calculator below can used to calculate the hydraulic and shaft power of a pump using Imperial units:
