What is measurement is Pa?
Pa is the metric unit for pressure, Pascal. It is one Newton per square meter. Atmospheric pressure is approximately 101 kPa (101 000 Pa), which is 14.7 psi (pounds per square inch) in Imperial units. The air pressure in car tires is usually about twice that (32 psi, 220 kPa).
What is the formula to convert psi to bar?
One formula used to convert psi to bar is: 1 psi = (32.174 lbm /1 lbf s2)x(0.45359237 kg /1 lbm)x(144 in2/1 ft2)x(1 ft /0.3048 m) x(1 m s2 /105 kg) = 0.06894747 bar So 1 bar = 14.503795 psi The Math behind it. As psi is an imperial unit and bar is metric unit, we some constants 1 lb = 0.45359237 kg 1 ft = 0.3048 m 1 ft2 = 12 in x 12 in = 144 in2 And we have to rearrange some units 1 bar = 105 Pa = 105 Nm-2 And N = kg ms-2 so 105 Pa = 105 kgm-1s-2 Also note when applying newton's second law using imperial units we need to use a gravity constant 32.174 lbm /1 lbf s2 Metric m x a = F 1 kg x 9.81 ms-2 = 9.81 N Imperial units m x a = F 1 lbm x 32.174 fts-2 ≠ 32.174 lbf need to use gravity constant gc m x (a/gc) = F 1 lbm x (32.174 fts-2 / (32.174 lbm /1 lbf s2) = 1 lbf
What is means by 1Gpa?
G = giga Pa = Pascal (a measurement of pressure or force) 1 GPa = 1000 MPa = 1 000 000 KPa = 1 000 000 000 Pa 1 GPa = 10,000 Bars = 145,037.74 psi = 9,869.2327 ATM = 7 500 616.8 mmHg
Can you tell me what MPa is the abbreviation for?
MPa is a metric (SI) unit for pressure, or force per unit area. Pa is the Pascal, which is one Newton of force applied to one square meter of area (1 N/m2). MPa is a mega-Pascal, or one million Pascals. Since atmospheric pressure is 101 000 pA, or 101 kPa(approximately 14.7 psi), this is approximately 9 atmospheres (around 150 psi).
Program in c using pointers to interchange 2 values without using third variable?
swap (int *pa, int *pb) { *pa ^= *pb; *pa ^= *pa; *pa ^= *pb; }
